摘要

Stereodivergent hydrosilylation of terminal alkynes (RC CH; R= Ph, p-tolyl, Cy, n-hexyl) with hydrosilanes (HSiMe2Ar; Ar Ph, 3, 5-(CF3) 2C6H3, 4-CF3C6H4, 4-MeOC6H4) has been examined using ruthenium catalysts.(E)-selective reactions giving (E)-RCH CHSiMe2Ar proceed in over 99% selectivity in the presence of a catalytic amount of RuHCl (CO)(PPh3) 3. On the other hand,(Z)-selective reactions are successfully conducted in 91– ...
