摘要

Abstract A facile and highly efficient protocol for 1, 3-dipolar cycloaddition of in situ generated nitrile oxides with terminal alkynes catalyzed by copper-doped silica cuprous sulfate (CDSCS) as a new and convenient heterogeneous nano catalyst is described. In this protocol,'click'cycloaddition of various structurally diverse alkynes and imidoyl chlorides in the presence of CDSCS and NaHCO 3 in a solution of i-PrOH/H 2 O (1: 1, V/V) furnishes ...
