A heterogeneous gold(I)-catalyzed regioselective hydration of propargyl acetates has been developed that proceeds smoothly in 1,4-dioxane at room temperature in the presence of 1 mol% diphenylphosphine-modified MCM-41-anchored gold(I) complex [Ph₂P-MCM-41-AuSbF₆] as catalyst and provides an efficient and practical approach for the synthesis of a variety of α-acyloxy methyl ketones with high atom economy, good to excellent yield, and high functional group tolerance. This new immobilized gold(I) catalyst can readily be obtained by a simple preparative procedure from commercially available reagents, and recovered via a filtration process and reused at least seven times without apparent loss of activity.

已经开发出了炔丙基乙酸酯的多相金（I）催化区域选择性水合，可在室温下在1 mol％二苯膦改性的MCM-41固定的金（I）络合物存在下，在1,4-二恶烷中平稳进行。₂ P-MCM-41-AuSbF ₆ ]作为催化剂，为合成具有高原子经济性，良好至优异收率和高官能团耐受性的各种α-酰氧基甲基酮提供了一种高效实用的方法。这种新的固定化金（I）催化剂可以通过简单的制备程序轻松地从市售试剂中获得，并通过过滤过程进行回收，并至少重复使用7次，而活性没有明显降低。
