2-disubstituted alkenylsilanes. The obtained alkenylsilane was subjected to reaction with α,β-unsaturated carbonyl compounds in the presence of a rhodium catalyst to undergo conjugate addition. One-pot hydrosilylation-conjugate addition with a rhodium catalyst was also performed.
铑催化的内部炔烃的氢化硅烷化提供了(E)-1,2-二取代的烯基硅烷。在铑催化剂的存在下,使所获得的烯基硅烷与α,β-不饱和羰基化合物反应以进行共轭加成。还进行了用铑催化剂的一锅加氢硅烷化-共轭物的添加。
