Resumen
The objectives of this study were to evaluate the alleviating effects of the isoquinoline alkaloid berberine (BBR) on the energy balance (EB), glucose and insulin metabolism, and liver functionality in transition dairy goats, as reflected by blood metabolites and enzymes. Twenty-four primiparous Saanen goats were randomly allocated to four groups. Goats in each group received, ad libitum, the same basal diet during the pre- and post-partum periods of evaluation. Goats received daily0, 1, 2, or 4 g BBR (coded as CON, BBR1, BBR2, and BBR4, respectively). Dry matter intake (DMI) and milk yield were recorded daily. Blood samples were collected on days −21, −14, −7, 0, 7, 14, and 21 relative to kidding, and individual body condition scores (BCSs) were also recorded. Supplementation with either BBR2 or BBR4 increased (p < 0.05) pre- and post-partum DMI, increasing (p < 0.05) the intakes of net energy for lactating and metabolizable proteins. BBR2 and BBR4 increased (p < 0.05) post-partum milk production as well as fat-corrected milk (FCM), energy-corrected milk (ECM), and feed efficiency, indicating the alleviating effect of BBR on the negative energy balance (NEB) in transition goats. The daily ingestion of either 2 or 4 g BBR reduced (p < 0.05) plasma aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) and increased (p < 0.05) the dynamic change in the liver activity index (LAI) and liver functionality index (LFI), implying its hepatoprotective effect on transition goats. Overall, the results suggest that BBR supplementation of at least 2 g/d may help to ameliorate insulin resistance (IR) and fat metabolism disorders initiated by the NEB in transition dairy goats.

Resumen
The aromatic hydroxyaldehydes 3a-3g, 5a-5f, 8 , 10 can be prepared by the action of BCl3, BBr3 or trifluoromethanesulfonic acid, on the aryl formates 1a-1f, 4a-e, 7, 9 via Fries rearrangement. BBr3 is more effective than BCl3. The activating ability of BBr3 can be improved by addition of FeCl3. Rearrangements which are induced by trifluoromethanesulfonic acid can give rise to the formations of regioisomers, which might be different from the products formed when the reaction is performed with Lewis acids. The yields of the aldehydes are lowered by subsequent condensation reactions. This view was confirmed by the isolation of a condensation product, which was characterized as a dibenzo[a,j]xanthene derivative 6 by crystal structure analysis. For the Fries rearrangement of formyl groups a new mechanism is proposed. 2-Hydroxy-1-naphthaldehyde 5c can be obtained in good yield from formic acid, BBr3, and 2 -naphthol.

Resumen
Abstract Peralkylated 2,3,4,5-tetracarba-mdo-hexaboranes(6) 1 react with boron tribromide, BBr3, via selective exchange of the alkyl substituent in 6-position to give the corresponding new 6- bromo derivatives 2 in quantitative yield. The 6-iodo derivatives 2(1) can be prepared in the same way using BI3. Treatment of the carbaboranes 2 with Li Et3BH leads to the 1,2,3,4,5- pentaalkyl-2,3,4,5-tetracarba-inido-hexaboranes(6) 3. 1,3,4,6-Tetraethyl-2,3,4,5-tetracarbaw do-hexaborane(6) 4 reacts with BBr3 via degradation of the carbaborane cage to give EtBBr2, and (Z)-1,4-bis [bis(dibromoboryl)]-3-hexene 5. A new bis(diethylboryl)-substituted dialkenyl(bromo)borane 8 was prepared, but attem pts failed to convert it into a 1-bromo- or 6-bromo-mdo-C4B2-carbaborane. Treatment of 1,1-dialkyl-3-diethylboryl-4-ethylstannoles 9 with a large excess of BBr3 also affords 5, whereas 6-bromo-l,3,4-triethyl-2,3,4.5-tetracarbamdo- hexaborane(6) 11 was isolated in low yield (<5%) from the reaction between 9 and BBr3 (slight excess)

Resumen
An extremely bulky secondary amine, HN(Ar†)(SiPr3i) HL† (Ar† = C6H2{C(H)Ph2}2Pri−2,6,4) has been synthesised and deprotonated with KH in toluene, to afford the potassium amide [KL†(η6-toluene)], which was structurally authenticated. Reaction of this with BBr3 and AlBr3, reproducibly gave the crystallographically characterised amido bromo-borane, [L†B(H)Br], and aluminacycle, [AlBr2{κ2-C,N-N(H)(SiPr3i){C6H2[CPh2][C(H)Ph2]Pri-2,6,4}}], respectively, via ligand C–H activation processes. The known secondary amines, HN(Dip)(Mes) (HLMes) and HN(Dip)(Trip) (HLTrip) (Dip =2,6-diisopropylphenyl, Mes = mesityl, Trip = 2,4,6-triisopropylphenyl), have been structurally characterised, and deprotonated to give the in situ generated lithium amides, [Li(LMes)] and [Li(LTrip)]. Reaction of these with BBr3 and AlBr3 has given the amido group 13 element halide complexes, [LMesBBr2] and [LAlBr2(THF)] (L = LMes or LTrip), the crystal structures of all of which have been determined. Synthetic routes to two new bulky amidine pro-ligands, ArN = C(But)-N(H)Ar, Ar = C6H2{C(H)Ph2}2Me-2,6,4 (Piso*H) or C6H2Pr2i(CPh3)-2,6,4 (Piso″H), have been developed, and the compounds crystallographically characterised. Deprotonation of Piso″H gave the potassium amidinate, [K(Piso″)], which was reacted with BBr3 to give [(Piso″)BBr2]. Reaction of Piso″H with AlMe3 afforded [(Piso″)AlMe2], which, when treated with I2 yielded [(Piso″)AlI2], the crystal structure of which was determined. Reductions of all of the prepared amido and amidinato group 13 element(iii) halide complexes were attempted using a variety of reducing reagents, with a view to prepare boron(i) or aluminium(i) complexes. While these were not successful, this study does offer synthetic inorganic chemists a variety of new very bulky anionic N-donor ligands, and boron/aluminium halide complexes thereof, for use in their own research.

Resumen
Dopant induced grain growth in LPCVD polysilicon films has been investigated using BBr3 as the diffusion source at 900 and 950 °C. TEM and sheet resistance measurements indicate rapid growth under such doping conditions. Results are compared with the grain growth observed during (a) PBr3 doping of similar films, and (b) during anneals in ambients containing 1% oxygen in nitrogen, similar to that used during BBr3 or PBr3 doping. The results clearly demonstrate the rapid grain growth induced by both types of dopants, although phosphorus is more effective in inducing this grain growth.

Resumen
4,22-Dimethoxy[2.10]metacyclophan-1-yne was prepared by bromination of [2.10]metacyclophan-1-ene followed by the dehydrobromination of the bromine adduct with KOBu-t. Treatment of 4,22-dimethoxy[2.10]metacyclophan-1-yne with BBr3 in CH2Cl2 at room temperature led to the demethylation and a successive intramolecular cyclization reaction to afford a novel [10](2,9)-5a,11a-benzofuro-5a-bora-11-bromochromenophane in good yield. Similar treatment of a mixture of the corresponding meso- and dl-1,2-dibromo-4,22-dimethoxy[2.10]metacyclophane with BBr3 in CH2Cl2 under the same conditions described above afforded cis-4b,9b-dihydro[10]benzofuro[3,2-b]benzofuranophane in 83% yield.

penta-O-Methylquercetin (2) was prepared by permethylation of quercetin (1). Selective demethylation of 2 using either BBr3 or BCl3/TBAI ( tetra-butylammonium iodide) gave five O-methylquercetins (3-6), with satisfactory yields. The reaction can be easily scaled-up. We established an efficient and large-scale preparation of O-methylquercetins.

Resumen
On heating bis(diiodoboryl)methane (1c) and 1,1-bis(diiodoboryl)alkanes 1i, l (alkane = propane, butane) under reduced pressure elimination of BI3 takes place and the corresponding 1,3,5-triiodo- 1,3,5-triboracyclohexane derivatives 2c; 2i, i’; 2l, l’ are formed. Starting with bis(dichloroboryl)- and bis(dibromoboryl)methane (1a, 1b) only small amounts of the trimerization products (H2C-BCl)3 (2a) and (H2C-BBr)3 (2b) are detectable which can not be separated from 1a,b and by-products. Reaction of 1,3,5-trichloro-2,4,6-trimethyl-1,3,5-triboracyclohexane (2d) with BBr3 provides the corresponding bromo derivative 2e in high yield. An attempt to react 2,4-bis(dichloroboryl)-3-chloro- 3-borapentane (4d) with 1,1-bis(trimethylstannyl)-2,2-diphenylethene does not lead to the expected trichloro-triboracyclohexane, but the divinylchloroborane ClB(CH=CPh2)2 6a, is formed. The compositions of the products follow from analytical data and X-ray structure analyses of 2i, 2c, 2e, and 6a.

Resumen
The reaction of tetrapyrrolidinodiborane(4) (1) with BBr3 in a 1:1 molar ratio yields a mixture of 1,2-dibromo-1,2- dipyrrolidinodiborane(4) (2) and bromotripyrrolidino- diborane( 4) (3), while a 1:2 molar ratio leads in Et2O to compound 2 as the main product along with a small amount of [(C4H8N)2B2Br3(OEt)] (4). The new compounds have been characterized by NMR and MS data, as well as by X-ray structure analyses of 2 and 4, of which the former exhibits an interesting polymorphism phenomenon.
