Abstract

A highly reactive intermediate N-sulfonyl acetylketenimine was generated from a 3-butyn-2-one participating CuAAC/ring-opening method. Its high reactivity due to bearing two EWGs allowed us to offer the first example of a reaction between ketenimine and amide to synthesize N-sulfonyl amidines efficiently.
