通过后合成方法制备了一种含有 Au(III) 希夫碱络合物的 MOF，该络合物排列在孔壁上。含Au(III)的MOF对于液相多米诺偶联和环化反应具有高活性和选择性，反应后Au(III)物质保留，并且催化剂完全可回收。这比迄今为止报道的均相催化剂和金负载催化剂具有更高的活性。明确的 Au(III) 位点对于解离 H2 具有活性，并被证明对于 1,3-丁二烯气相选择性加氢成丁烯具有活性。
A MOF containing an Au(III) Schiff base complex lining the pore walls has been prepared by a post-synthesis method. The Au(III)-containing MOF is highly active and selective for domino coupling and cyclization reactions in liquid phase, the Au(III) species remain after the reaction, and the catalyst is fully recyclable. This gives higher activity than homogeneous and gold-supported catalysts reported up to now. The well-defined Au(III) sites are active for dissociating H2and proved to be active for the gas-phase selective hydrogenation of 1,3-butadiene into the butenes.
