heterogeneous gold(I)-catalyzed hydrohydrazidation of terminal alkynes with diverse hydrazides has been developed in chlorobenzene at 60 °C by using an MCM-41-immobilized diphenylphosphine gold(I) complex [Ph2P-MCM-41-AuNTf2] as the catalyst, providing a novel and practical method for the synthesis of a wide variety of substituted keto-N-acylhydrazones in good to excellent yields. This heterogenizedgold(I) catalyst
