Abstract

Demonstrates that N-(pentafluorophenyl)-2-phenylethynamine undergoes acid dissociation in aqueous solution at a specific pKa. Generation of ynamine by flash photolysis of aminocyclopropenone; Rate profile of the reaction of the ynamine to the ketenimine; Least-squares analysis of the break in the basic portion of the rate profile.
