乙硅烷 (1a-e) 在钯催化剂存在下与 1,3-二烯 (2a-d) 反应，以高产率区域选择性和立体选择性地生成二聚双硅烷化产物 (3a-k)。 Pd(DBA)2在室温下以DMF或二恶烷为溶剂表现出高催化活性。没有发生交叉硅烷化。
Disilanes (1a-e) react with 1,3-dienes (2a-d) in the presence of a palladium catalyst to give dimerization-double silylation products (3a-k) regio- and stereoselectively in high yields. Pd(DBA)2 shows high catalytic activity in DMF or dioxane as the solvent at room temperature. No crossover silylations occur.
