Oliveira, Marcelo Ribeiro Leite; Franca, Eduardo de Faria; Novais, Celice; Guilardi, Silvana; Machado Jr., Iterlandes; Ellena, Javier; Amim Jr., JorgeFive new complexes of general formula: [Ni(RSO2NCS2)(dppe)], where R = C6H5 (1), 4-ClC6H4 (2), 4-BrC6H4 (3), 4-IC6H4 (4) and dppe = 1,2-bis(diphenylphosphino)ethane and [Ni(4-IC6H4SO2NCS2)(PPh3)2] (5), where PPh3 = triphenylphosphine, were obtained in crystalline form by the reaction of the appropriate potassium N-R-sulfonyldithiocarbimate K2(RSO2NCS2) and dppe or PPh3 with nickel(II) chloride in ethanol/water....

Cunha, Leandro Marcos Gomes; Rubinger, Mayura Marques Magalhães; Oliveira, Marcelo Ribeiro Leite; Tavares, Eder do Couto; Sabino, José RicardoThe compounds (Ph4P)2[Zn(RSO2N = CS2)2] [Ph4P+ = tetraphenylphosphanium cation; R = CH3 (1b), CH3CH2 (2b), CH3(CH2)3 (3b) and CH3(CH2)7 (4b)] were synthesized by the reaction of RSO2N = CS2K2·2H2O (1a–4a) with Zn(CH3COO)2·2H2O and Ph4PCl. The IR data were consistent with the formation of bis(dithiocarbimato)zinc(II) complexes. The NMR spectra showed the expected signals for the cation and the dithiocarbimate an...

Tavares, Eder do Couto; Oliveira, Marcelo Ribeiro Leite; Janczak, Jan; Vieira, Camila Grossi; Alves, Leandro de Carvalho; Castro, Rodrigo AntunesFour zinc(II)-bis(trithiocarbimato) complexes with the general formula A2[Zn(RSO2NCS3)2] [A = Ph4P+: R = CH3 (1), 4-CH3C6H4 (2); A = Bu4N+: R = CH3 (3), 4-CH3C6H4 (4)] were obtained by the reaction of sulfur with the correspondent zinc(II)-bis(dithiocarbimato) complexes. Additionally, the compound (Ph4P)2[(CH3SO2NCS2)2S)] (5) was prepared from the potassium methylsulfonildithiocarbimate by oxidation with iodine...

Oliveira, Marcelo Ribeiro Leite; Vieira, Heulla P.; Perpétuo, Genivaldo Julio; Janczak, Jan; Bellis, Vito M. DeThree new complexes of the general formula: [Ni(PPh3)2(RSO2N_/CS2)] where R_/2-CH3C6H4 (1), 4-CH3C6H4 (2) and 4-BrC6H4 (3) were obtained in crystalline form by the reaction of the appropriate potassium N-R-sulfonyldithiocarbimates (K2(RSO2N_/CS2)) and triphenylphosphine with nickel(II) chloride in ethanol_/water. The 1 complex crystallizes in the centrosymmetric space group of the triclinic system with two mole...

Oliveira, Marcelo Ribeiro Leite; Perpétuo, Genivaldo Julio; Janczak, Jan; Rubinger, Mayura Marques MagalhãesTwo new zinc(II)-complexes, dithiocarbimato (Ph4P)2[Zn(CH3SO2N@CS2)2] (1) and trithiocarbimato (Ph4P)2[Zn(CH3SO2N@CS3)2] (2), were obtained in the crystalline form by the reaction of potassium N-methylsulfonyldithiocarbimate (RSO2N@CS2K2) with zinc(II) acetate dihydrate and tetraphenylphosphonium chloride in dimethylformamide. Both complexes crystallize in the monoclinic system. The central Zn(II) ion has a dis...

Amim, Raquel S.; Oliveira, Marcelo Ribeiro Leite; Perpétuo, Genivaldo Julio; Janczak, Jan; Miranda, Liany Divina LimaThe reaction of 4-iodobenzenesulfonamide or 4-fluorobenzenesulfonamide with CS2 and KOH in dimethylformamide yielded the potassium N-R-sulfonyldithiocarbimates, K2(RSO2N@CS2) [R = 4-IC6H4 (1) and 4-FC6H4 (2)]. These salts reacted with K2[PtCl4] in water/methanol to yield complex anions bis(N-R-sulfonyldithiocarbimato) platinate(II), which were isolated as their tetrabutylammonium salts, (Bu4N)2[Pt(RSO2N@CS2)2] ...
