A copper-catalyzed regioselective Markovnikov 3,4-hydrosilylation of 2-substituted 1,3-dienes has been accomplished. A wide range of 2-substituted 1,3-dienes and trihydrosilanes are compatible under the optimal conditions. The bisphosphine ligand with a rigid backbone provides the Markovnikov 3,4-hydrosilylation product in better yield and selectivity. Besides, the synthetic utilities of the allylsilanes
已经完成了铜催化的 2-取代 1,3-二烯的区域选择性马尔科夫尼科夫 3,4-氢化硅烷化。广泛的 2-取代 1,3-二烯和三氢硅烷在最佳条件下是相容的。具有刚性骨架的双膦配体为 Markovnikov 3,4-氢化硅烷化产物提供了更好的产率和选择性。此外,烯丙基硅烷的合成效用也通过其灵活的衍生化得到证明。
