Reactions of [Pt(PEt3)3] (1) with the silanes HSiPh3, HSiPh2Me and HSi(OEt)3 led to the products of oxidative addition, cis-[Pt(H)(SiPh3)(PEt 3)2] (2), cis-[Pt(H)(SiPh2Me)(PEt 3)2] (3), cis-[Pt(H){Si(OEt)3}(PEt 3)2] (cis-4) and trans-[Pt(H){Si(OEt)3} (PEt3)2] (trans-4). The complexes cis-4 and trans-4 can also be generated by hydrogenolysis of (EtO)3SiSi(OEt)3 in the presence of 1. Furthermore, the silyl compounds cis-4 and trans-4 react with B(C6F5)3 and CH3CN by hydride abstraction to give the cationic silyl complex trans-[Pt{Si(OEt) 3}(NCCH3)(PEt3)2][HB(C 6F5)3] (8). In addition, the reactivity of the complexes cis-4, trans-4 and 8 towards alkenes and CO was studied using NMR experiments.
