Abstract
Abstract A THF solution of diazopropyne was obtained in 60% yield by the reaction of a 30% aqueous solution of methylamine with N, N′-dinitroso-N, N′- dipropargylterephthalodiamide. The reactions of diazopropyne with methyl acrylate and methyl methacrylate giving various ethynylpyrazolines as well as its CuCl-catalyzed decomposition in the presence of norbornene or norbornadiene yielding ...
