abstract

  • The corresponding pyrroles and their N-vinyl derivatives were obtained by the catalyzed (by an MOH-DMSO superbase) reaction of acetylene and its crypto forms (vinyl chloride, 1,2-dichloroethane) with alkyl-2,4-, alkyl-2,5-, and alkyl-3,4-dimethylphenylketoximes. Reaction intermediates — O-vinylketoximes — were detected.
