A simple method is described for the synthesis of 1-arylprop-1-ynes directly from aromatic aldehyde p -tosylhydrazones by using calcium carbide as an acetylene source. The salient features of this protocol are its use of a readily available and easily handled source of acetylene, its operational simplicity, its high yield, and its broad substrate scope.
