Stereoselective Synthesis of (<i>E</i>)- and (<i>Z</i>)-Triethoxy(vinyl-<i>d</i>₂)silanes by Hydrosilylation of Acetylene-<i>d</i>₂

Abstract

The hydrosilylation of deuterated acetylene with triethoxysilane can be directed to the synthesis of either cis or trans triethoxy(vinyl-d2)silanes by an appropriate choice of metal catalyst. In addition, we have demonstrated the viability of designing hydrosilylation−arylation sequential processes in which acetylene can be converted into styrenes or stilbenes using the same Pd catalyst for both reactions.
