Three new disilaplatinacyclopentane complexes, (Me2S)Pt[(SiMe2)(2)C6H4](2) (1), (MeSCH2CH2CH2-SMe)Pt[(SiMe2)(2)C6H4](2) (2), and (MeSCH2CH2CH2SMe)Pt[(SiMe2)(2)C6H4] (3), were prepared and characterized by the reaction of (PtMe2)(2)(mu-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.
