摘要：

The activation of Ph2HSiSiHPh2 and Me3SiSiMe3 at [Pt(PEt3)(3)] (1) yielded the products of oxidative addition. The formation of [Pt(SiHPh2)(2)(PEt3)(2)] (2) as a mixture of the cis and trans isomers appears to proceed quantitatively, whereas a conversion to give cis-[Pt(SiMe3)(2)(PEt3)(2)] (3) was not complete. Treatment of 1 with one equivalent of H2SiPh2 led to cis-and trans-[Pt(H)(SiHPh2)(PEt3)(2)] (cis-4, trans-4) together with the dinuclear complex [(Et3P)(2)(H)Pt(mu-SiPh2)(mu-eta(2)-HSiPh2)Pt(PEt3)] (5). In contrast, HSiMe3 reacts with [Pt(PEt3)(3)] to yield cis-[Pt(H)(SiMe3)(PEt3)(2)] (7) exclusively. Catalytic reactions of dihydrogen with the disilanes Ph2HSiSiHPh2 or Me3SiSiMe3 in the presence of catalytic amounts of [Pt(PEt3)(3)] (1) led to the products of hydrogenolysis, H2SiPh2 and HSiMe3. The conversion of Me3SiSiMe3 is much slower and needs higher temperature to proceed.
