Full textThe synthesis of simple, and also bipodal N-substituted N'-acyl- and N'-aroylthiourea ligands has been investigated, along with aspects of their co-ordination chemistry to Pt(II) and Pd(II). The ligands are commonly produced by reacting a secondary or primary amine with an acyl or aroyl isothiocyanate. This synthesis requires nucleophilic addition of the amine to the thiocarbonyl carbon of the acyl or aroyl isothocyanate. However, a competitive side-reaction frequently occurs because the amine nucleophile can attack the carbonyl carbon of the isothiocyanate reagent instead. This leads to substitution of the isothiocyanate moiety and the formation of an N-substituted amide.

Full textThe feasibility of combining this ring-opening reaction to insertion polymerization to generate new block co-polymers is subsequently investigated, and it forms the primary objective of the study.
The dual-functional palladium(II) complex (bipy)Pd(CH3)(NCCH 3)+OTf- is found to mediate a novel, single-step coupling of insertion and ring-opened monomers (CO, norbornene, THF) into new polymers. This coupling process follows an unusual route, involving enol lactone as an intermediate, and facilitated by weak Lewis acid. Similar coupling chemistry has been applied to the synthesis of polyTHF end-capped with a small polynorbornene fragment.

Este trabalho contempla a preparação de novas espécies de paládio (II), ciclometaladas ou não, a partir dos precursores [Pd(dmba)(æ-X)]2 (dmba = N,N-dimetilbenzilamina; X = Cl, N3, NCO) e [PdCl2(CH3CN)2]. Os complexos [Pd(dmba)(X)(tu)] (tu = tiouréia; X = Cl, N3, NCO) foram obtidos via clivagem dos ciclopaladados diméricos [Pd(dmba)(æ-X)]2 pelo ligante tiouréia, bem como os compostos [Pd2(dmba)2(æ-NCO)(æ-L)] (L = 2-qnS = 2-quinolinatiolato; L = 8-qnS = 8-quinolinatiolato) mediante substituição parcial do cianato em ponte pelos ligantes 2-qnS e 8-qnS, respectivamente. Os dados oriundos da investigação espectroscópica dos mesmos segundo as técnicas de espectroscopia vibracional na região do IV, RMN de 1H e 13C permitiram diagnosticar o modo de coordenação dos ligantes dmba, tiouréia, 2-quinolinatiolato, 8-quinolinatiolato e pseudo-haletos ao paládio. Tais dados, juntamente com outros da literatura e analíticos, confirmaram os monômeros [Pd(dmba)(X)(tu)] (X = Cl, N3, NCO) e os compostos binucleares [Pd2(dmba)2(æ-NCO)(æ-L)] (L = 2-qnS, 8-qnS).

From IR data, it was evidenced the terminal coordination of the N3 and NCO groups in [Pd(dmba)(X)(tu)] complexes, whereas in the complexes of the type [Pd2(dmba)2(æ-NCO)(æ-L)] the NCO, 2-qnS and 8-qnS ligands were found in theirs bridging forms. The results obtained from 1H, 13C NMR signals showed significant shifts related to the free ligands, indicating their coordination to Pd.

A quimioterapia é uma das principais formas de combate ao câncer. Sendo assim, muitas pesquisas vêm sendo feitas com o objetivo de desenvolver compostos que solucionem, ou minimizem, os problemas decorrentes deste tipo de tratamento, como os efeitos colaterais e a resistência que as células desenvolvem aos medicamentos. Os pirazóis e seus complexos são conhecidos por possuírem atividade antitumoral, antiinflamatória, antibacteriana e antipirética. Tendo em vista estas propriedades, ligantes pirazólicos foram utilizados na síntese de complexos de paládio(II) com a finalidade de obter compostos com atividade antitumoral. A escolha deste metal foi baseada na similaridade entre sua química de coordenação e a da platina(II), cujos complexos, como a cisplatina e a carboplatina, são amplamente utilizados como agentes antitumorais. Neste contexto, o presente trabalho descreve a síntese, caracterização e avaliação da atividade antitumoral de duas séries de compostos paládio(II) de fórmula geral [PdX2(HdmIPz)2] {HdmIPz = 3,5-dimetil-4-iodopirazol; X = Cl (1), Br (2), I (3), SCN (4)} e [PdX2(HmPz)2] {HmPz =4-metilpirazol; X = Cl (5), Br (6), I (7), SCN (8)}. Os compostos foram caracterizados por análise elementar, espectroscopia vibracional na região do infravermelho, ressonância magnética nuclear de 1 H e 13 C{ 1 H}, termogravimetria e análise térmica diferencial. Os complexos sintetizados e os ligantes livres foram submetidos a testes de atividade citotóxica frente a células tumorais murinas. A cisplatina foi usada como droga padrão, sendo submetida às mesmas condições. A citotoxicidade dos compostos 1-4 também foi avaliada frente a macrófagos peritoneais de camundongos
Chemotherapy is one of the main methods of treating cancer. Thus, much research has been undertaken with the aim of developing compounds that can solve or minimize the problems caused by this type of treatment, as the side effects and cell resistance. Pyrazoles and their complexes are known to possess antitumor, anti-inflammatory, antiamoebic, antibacterial, antipyretic activities. Considering these properties, pyrazole ligands were used in the synthesis of palladium(II) complexes with the aim to obtain compounds displaying antitumor activity. The choice for using this metal was based on the similarity of its coordination chemistry to that of platinum(II) whose compounds, such as cisplatin and carboplatin, are widely used as antitumor agents. In this context, this work describes the synthesis, characterization and investigation of the antitumor activity of two series of palladium(II) complexes of general formulae [PdX2(HdmIPz)2] {HdmIPz = 3,5-dimethyl-4-iodopyrazole; X = Cl (1), Br (2), I (3), SCN (4)} e [PdX2(HmPz)2] {HmPz =4-methylpyrazole; X = Cl (5), Br (6), I (7), SCN (8)}. The compounds were characterized by elemental analysis, infrared vibrational spectroscopy, 1 H and 13 C{ 1 H} nuclear magnetic resonance, thermogravimetry and differential thermal analysis. The complexes and the free ligands were tested for cytotoxic activity against murine tumor cells. Cisplatin was used as standard drug, being subject to the same conditions. The cytotoxicity of compounds 1-4 was also evaluated towards peritoneal macrophages of mice
