Abstract
Functionalized hyper-cross-linked polymer-supported metal complexes have been developed as heterogeneous catalysts for organic synthesis and have attracted much attention. In this regard, a phosphine-based hyper-cross-linked polymer-supported neutral gold(I) complex, Au@HCPs-PPh3, which is synthesized by incorporation of [(Me2S)AuCl] into a phosphine-based hyper-cross-linked polymer, is proven to be an efficient and general heterogeneous catalyst for the regioselective hydration of a series of alkynes to ketones. Furthermore, the synthesized catalyst is recycled six times without an obvious decrease in the catalytic activity.
