Abstract:
The highly electron-deficient cyanocarbons tetracyanoethene (tcne) and, to a lesser extent, tetracyanoquinodimethane (tcnq), display a fascinating chemistry with transition metal substrates. In particular, the [2 + 2]-cycloadditions of the cyanocarbons with alkynyl- or poly-ynyl–metal complexes have been extensively studied by the author’s group. These reactions proceed via polar adducts to give σ-cyclobutenyl complexes, which then undergo facile ring-opening (retro-electrocyclic) reactions to form the corresponding butadienyl derivatives. In some cases, further reactions can occur by displacement of weakly bound ligands from the metal centre. The subsequent chemistry of these derivatives has been only cursorily investigated, while related studies of organic analogues have produced molecules with interesting electronic and optical properties.

Abstract:
In this paper, the nature of interactions between two cyanocarbons—tetracyanoethylene (TCNE) and fumaronitrile (FN)—and a series of four secondary amines possessing a general formula C4HxN (x = 5–11) is thoroughly scrutinized. For all of the TCNE–amine pairs, tricyanovinylation (TCV) reaction is observed; however, only for pyrrole, it is accompanied with a visible charge-transfer (CT) complex formation—no such chemical individuals, characteristic for TCNE, have been noticed for aliphatic and alicyclic amines. On the contrary, FN forms such complexes with all the amines studied. Interestingly, a rather unexpected reaction of FN with alicyclic amines has been observed. The recorded electron paramagnetic resonance (EPR) spectra indicate the presence of both TCNE●− and FN●− radicals in the analyzed samples, assigned to a complete charge (electron) transfer process within the CT complexes, whose efficiency can be additionally enhanced by photoirradiation. The origination of the former radical, whose presence is observed also in the TCNE–diethylamine mixture, is as well proposed to result indirectly from the TCV reaction, occurring for this system. Finally, the superhyperfine structure of EPR spectra, indicating the existence of some secondary interactions of the radicals with surrounding compounds, is discussed. Formation of CT complexes and tricyanovinylates has been investigated and characterized with UV–Vis spectroscopy, while the presence of (cyano)radicals in the analyzed mixtures has been evidenced by (photoinduced) EPR measurements. Interpretation of the experimental results is also supplemented with computer simulations including density functional theory calculations.

Abstract:
Chapter 1 outlines the potential application of metal alkynyl complexes and then describes the different methods in the literature for the synthesis of alkynyl, poly-ynyl and homo- and hetero-metal complexes. Their chemistry will then be discussed. This Chapter concludes with an outline of the work to be described in the remainder of the thesis. Chapter 2 describes a series of complexes containing a new tricyanovinylethynyl (3,4,4-tricyanobut-3-en-1-ynyl) ligand obtained by direct substitution of a CN group in tetracyanoethene by ethynyl complexes M(C=CH)(PP)Cp' [M = Ru, Os, (PP)Cp' = (PPh₃)₂Cp; M = Ru, PP = dppe, Cp' = Cp, Cp*]. The reactions proceed in higher yield as the metal environment becomes sterically larger and more donating; the normal [2 + 2]-cycloaddition / ring-opened product M{C[=C(CN)₂]CH=C(CN)₂}(PP)Cp' is also formed in some cases. The diynyl Ru(C=CC=CH)(dppe)Cp* reacts with tcne to give only the ring-opened adduct Ru{C=CC[=C(CN)₂]CH=C(CN)₂}(dppe)Cp*. Protonation of Ru{C=CC(CN)=C(CN)₂}(dppe)Cp* (10) afforded the vinylidene. A second transition metal fragment {MLn} [{MLn} = Ru(PPh₃)₂Cp, M'(dppe)Cp* (M' = Ru, Os), RuCl(dppe)₂] can be added to the CN group trans to the first. Compound 10 ready undergoes substitution of the 3-cyano group by nucleophiles. Some unexpected rearrangements and formation of O- and N-heterocyclic compounds were also found. Chapter 3 describes reactions between 1,2 dichlorohexafluorocyclopentene and Ru(C=CH)(dppe)Cp* (1) or Ru(C=CC=CLi)(dppe)Cp* which give Ru(C=C-c-C₅F₆Cl-2)(dppe)Cp* (36) and Ru(C=CC=C-c-C₅F₆Cl-2)(dppe)Cp*, respectively. Ready hydrolysis of 36 to Ru{C=C[c-C₅F₄Cl(O)]}(dppe)Cp* occurs, which can be converted to Ru{C=C(c-C₅F₄Cl[=C(CN)₂])}(dppe)Cp* by treatment with CH₂(CN)₂ / basic alumina. The cyano-fluorocarbon ligand in the latter is one of the most powerfully electron-withdrawing groups known. Chapter 4 describes the three methods of synthesising heterometallic carbon-chain complex {Cp*(dppe)Ru}C=CC=CC=CC{Co₃(μ-dppm)(CO)₇} (40), in two examples showing the first examples of Ru{(C=C)xI}(dppe)Cp* (x = 1, 2) being used in a cross coupling reaction with Ph₃ PAu(C=C)(₃-x)C{Co₃(μ-dppm)(CO)₇}. The reactivity of 40 with PPh₃, MeOTf, tcne, tcnq, Fe₂(CO)₉, NiCp₂ and Co₂(CO)₈ took place on either the C₈ bridge or on either metal centre. Chapter 5 discusses the reaction of 1 with oxalyl chloride which gave {Cp*(dppe)RuC=C}₂CO (52). This complex can be methylated to give [{Cp*(dppe)RuC=C}₂C(OMe)]OTf, which in turn can be protonated to the dication. Knövenagel condensation of 52 with CH₂(CN)₂ gave {Cp*(dppe)RuC=C}₂C{=C(CN)₂}. The reaction of 1 and bis(2,4-dinitrophenyl) oxalate afforded {Cp*(dppe)Ru}{c- C=C[C₆H₃(NO₂)₂]C(O)C(O)O}. The transmetallation reaction of {(Ph₃P)AuC=C}₂CO and RuCl(dppe)Cp unexpectedly gave the cyclic complex [1,4-{Cp(dppe)Ru}₂{c- COC(OMe)=CHCCH}]PF₆. Chapter 6 gives an account of the electrochemistry of many of these redox-active compounds and examines the UV-Vis absorption of the more polarised compounds. Some discussion of the various observed trends is presented. There is also a future direction of this chemistry given at the end of this work.

Abstract Reaction of complexes [PPN]2[Fe(CO)2(CN)3Br] with [Na][SR] (R = C6H4Br , Ph) in CH3CN produced the mer-[PPN]2[Fe(CO)2(CN)3SR] complexes (R=C6H4Br (1), Ph (2) ) individually. Upon extended stirring complex 2 converted to the more stable complex [PPN]2[Fe(CO)2(CN)4] is attributed to the stronger σ-donor/π-donor properties of [SPh]-. Photolysis of CH3CN solution of complexes 1 and 2 the CO rearrangement to the more stable trans-[PPN]2[Fe(CO)2(CN)4], respectively. A number of thermally stable iron(II)-thiolate cyanocarbonyl complexes [FeII(CO)x(CN)y(SR)z]n- were synthesized. We conclude that the less electron-donating monodentate thiolate ligand bound to FeII metal stabilize the [FeII(CO)2(CN)3]- unit; the bidentate thiolate ligand bound to FeII metal stabilize the [FeII(CO)2(CN)2]0 unit; the tridentate thiolate ligand bound to FeII metal stabilize the [FeII(CO)2(CN)]+ unit. Notably, this study shows that certain total number of thiolate and cyanide ligand(3 ≦ y+z ≦ 4) ligated to FeII center provide significant stabilization to the iron(II)-thiolate cyanocarbonyl species [FeII(CO)x(CN)y(SR)z]n-. This study indicate that Nature’s choice of combinations of these ligand in hydrogenase.

Abstract Ruthenium-thiolate cyanocarbonyl compounds {[Na．2THF][Ru(CO)(CN)(S-C5H4N)2]}2（2）and [PPN][Ru(CO)(CN)(SC5H4N)2]（3）were prepared from nucleophilic reactions of [Na][N(SiMe3)2] and cis-[Ru(CO)2(S-C5H4N)2]（1）obtained from oxidation addition/acid- base reaction of Ru3(CO)12, Me3NO•2H2O, and 2-mercaptopyridine in THF. Complexes cis-[Ru-(CO)2(SC6H4NH2)2]（4）and [Ru2(μ-tdt)(CO)6]（5）( tdt＝toluene-3,4-dithiol ) were also synthesize. Complexes 1-5 were characterized by IR, UV/VIS, NMR spectra and X-ray crystallography. The IR spectrum of complex 2 in the aprotic THF displayed two weak υ( CN ) bands at 2098 and 2086 cm-1, and one strong υ( CO ) band at 1931 cm-1 support the dimeric struct -ure with two [Ru(CO)(CN)(SC5H4N)2]- units connected through CN-Na+-NC interactions, as observed in the single-crystal X-ray structure. Ethylation of complex 3 by electrophile [Et3O][BF4] occurring, initially, at the more acc- essible, delicately balanced nucleophilic site to yield the charge-controlled, collision product [Ru(CO)(CN)…Et…(S-C5H4N) (S-C5H4N)]（11）, and subsequently isomerizing to neutral [Ru(CO)(CNEt)(SC5H4N)2]（10）. The result demonstrated that the enhanced nucleophilicity toward electrophiles result from replacement of carbonyl ligand with cyanide ligand in comp- lex 1. In comparison with displaying the reverible redox process of the analogue [Fe(CO)(CN) -(S-C4H3N2)]-, the electrochemistry of complex 3 reveals an irreversible oxidation at 0.29V ( vs Ag/AgNO3).

Abstract Oxidative addition of diorganyl disulfides to the coordinatively unaturated, low-valent metal-carbonyl fragment [HFe(CO)4]－ produced fac-[(CO)3Fe(SR)3]－[R=S-C7H4SN (1)、S-C4H2O-o-CH3(2)], was employed as a “metallo chelating” ligand to synthesize [(CO)3Fe(S-C4H2O-o-CH3)3Ni(S-C4H2O-o-CH3)3Fe(CO)3] (3). The hexacoordinate Fe(Ⅱ) complex [PPN][(CO)(CN)Fe(S-C4H3S)2 (C8H6N4)](5)was prepared by the reaction of di-(thienyl)-disulfide, 2,2’-Bipyrimidine and [Fe(CO)4(CN)]－in CH3CN,The dinuclear Fe(Ⅱ)—thiolate cyanocarbonyl compound [PPN]2[(CO)2(CN)Fe(S,S-C6H3-m-CH3)]2(4),the promissing structural and functional model compound of the dinuclear iron active sites of [Fe] only hydrogenases isolated from D. desulfuricans and C. pasteurianum,was prepared by reaction toluene 3,4-dithiol,di-(thienyl)-disulfide and[Fe(CO)4(CN)] － in CH3CN. The dicyano-dicarbonyl iron(Ⅱ)-thiolate complex trans,cis-[(CN)2 (CO)2Fe(S, S-C-R]－[R=OEt(6)、N(Et)2(7)] was prepared from reaction of [Na][S-C(S)-R] and [(CN)2(CO)2Fe(Br)]－obtained from oxidative addition of cyanogen bromide to [Fe(CO)4(CN)]－。Photolysis of THF solution of complex(6)、(7)led to formation of the coordinate-unsaturated iron dicyanocarbonyl thiolate compound [(CN)2(CO)Fe(S, S-C-R]－[R=OEt、N(Et)2],the potential iron-site structural and functional model compound of iron-active site of [NiFe] hydrogenases isolated from D.gigas The complex[(CN)2(CO)Fe(S,S-C-R]－[R=OEt、N(Et)2] and NiA/NiC states [NiFe] hydrogenases from D.gigas exhibit the similar one band pattern in the νCO region and two band pattern in the νCN region individually,but different positions,which may be accounted for by the distinct electronic effects between[S-C(S)-R]－and thiocysteine lignads, The IR data shows that the CO vibrational frequency to the electron density changes around iron center is abount 2.6 times more sensitive than is νCN－, The complexes (6)、(7) were reobtained when the THF solution of [(CN)2(CO)Fe(S,S-C-R][R=OEt、N(Et)2] were exposed to CO atmosphere at room temperature individually.

Reaction of [PPN][FeBr(CN)2(CO)3] and [Na][SC2H5] in THF at ambient temperature produced the dinuclear iron(Ⅱ)-thiolate cyanocarbonyl cis,trans- [PPN]2[Fe(CO)2(CN)2(μ-SC2H5)]2 (1) and trans,cis-[PPN]2[Fe(CO)2(CN)2(μ- SC2H5)]2 (2). The electrophilic reaction of [Et3O][BF4] and complex 1 produced complex [PPN]2[Fe(CO)4(CN)(CNEt) (μ-SC2H5)2] (5). Upon reaction of complex 1 and [PPN] [SC2H5] in THF at room tempeture, the triply thiolate-bridged dinuclear Fe(Ⅱ) complex [PPN][Fe2(CO)4(CN)2(μ-SC2H5)3] (3) was produced via the extrusion of two σ-donor CN- ligands from Fe(Ⅱ)Fe(Ⅱ) centers of complex 1. The torsion angle of two CN- groups (C(5)N(2)and C(3)N(1)) in the complex 3 is 126.9°. The electrophilic reaction of CF3SO3Me and complex 3 propose to produce the complex [Fe(CO)4(CN)(CNEt)(μ-SC2H5)3] (7). Addition of [Na][benzophenone] to complex 3 produced complex [PPN]2[FeⅠ(CO)2(CN) (μ-SC2H5)]2(9). The Fe-S distances of complexes 1 and 2 (2.338(2) and 2.320(3) Å) are comparable, but the Fe(Ⅱ)-Fe(Ⅱ) distance contracts from 3.505 Å in complex 1 to 3.073 Å in complex 3 which is accompanied by a decrease in the ∠Fe-S-Fe angles from 97.14(5)° to 82.88(9)°. The considerably longer Fe(Ⅱ)-Fe(Ⅱ) distance 3.073 Å in complex 2, compared to the reported Fe-Fe distance of 2.6/2.62 Å in DdHase and CpHase, is attributed to the presence of the third bridging ethylthiolate, instead of π-accepting CO-bridging ligand as observed in [Fe]-only hydrogenase. The coordination chemistry of complexes 1 and 2 suggests that the total number of thiolate and cyanide ligands (3≦y+z≦4) surrounding Fe(Ⅱ) center provide significant stabilization to the Fe(Ⅱ)-carbonyl complexes [FeII(CO)x(CN)y(SR)z].
