A new protocol has been developed to synthesize N1-vinyl benzotriazoles from 1-arylmethylbenzotriazoles by treatment with arylaldehydes and LiN(SiMe3)2. The reaction proceeded smoothly in the absence of transition metals, showing excellent Z selectivity and broad substrate scope with good functional group tolerance.
