摘要：

Two geometrical isomers of 1,4-bis(trimethylsilyl)-1-buten-3-yne (cis- and trans-1) were subjected to catalytic hydrosilylation with HSiR3 (HSiMe2Ph or HSiMePh2) in the presence of catalytic amounts of late transition metal hydrides. Four kinds of regio-and stereoisomers of hydrosilylation products were formed: (R3Si)(Me3Si)C=C=CHCH2SiMe3 (2), (1Z, 3E)-CH(SiMe3)=C(SiR3)-CH=CHSiMe3 (3), (1Z,3E)-C(SiMe3)(SiR3)=CHCH=CHSiMe3 (4), and (1E,3E)-C(SiMe3)(SiR3)=CHCH=CHSiMe3 (5). The product selectivity was strongly affected by the geometry of 1 as well as the catalyst precursor employed. Compounds 2-5 could be prepared in over 93% selectivity, respectively.
