使用二氧化硅负载的笼型致密膦（Silica‐SMAP）用于铜催化的α，β-不饱和羰基和羧基化合物与聚（甲基氢硅氧烷）（PMHS）的共轭还原。该催化剂体系具有较高的活性和选择性，且反应后易于从反应混合物中分离。此外，该催化剂可重复使用而不损失其高催化活性或选择性。
A silica‐supported, cage‐type, compact phosphane (Silica‐SMAP) was used for the copper‐catalyzed conjugate reduction of α,β‐unsaturated carbonyl and carboxyl compounds with poly(methylhydrosiloxane) (PMHS). The heterogeneous catalyst system showed high activity and chemoselectivity, and was easily separable from the reaction mixture after the reaction. Furthermore, the catalyst was reusable without loss of its high catalytic activity or selectivity.
