Abstract

Three new disilaplatinacyclopentane complexes, (Me2S) Pt[(SiMe2)2C6H4]2 (1), (MeSCH2CH2CH2SMe)Pt[(SiMe2) 2C6H4]2 (2), and (MeSCH 2CH2CH2SMe)Pt[(SiMe2) 2C6H4] (3), were prepared and characterized by the reaction of (PtMe2)2(μ-SMe2)2 with 1,2-bis(dimethylsilyl)benzene in the presence of dialkylsulfide ligands. Catalytic hydrosilane reduction of carboxamides with 1,2-bis(dimethylsilyl) benzene was investigated in the presence of these new complexes, and the possible involvement of disilaplatinacycle dihydride species, "Pt(Si) 2(H)2(SR2)", stabilized by dialkylsulfides in catalysis was discussed.
