PYRROLES FROM KETOXIMES AND ACETYLENE. 28. INVESTIGATION OF VINYL CHLORIDE INSTEAD OF ACETYLENE FOR THE SYNTHESIS OF ARYLPYRROLES FROM ARYLETHANONE OXIMES
2-Arylpyrroles and their N-vinyl derivatives have been synthesized by reacting arylethanone oximes with vinyl chloride in a KOH-DMSO system at 140 deg C.

PYRROLES FROM KETOXIMES AND ACETYLENE. XXVI. THE SYNTHESIS OF NEW 2-ARYLPYRROLES
New representatives of the 2-arylpyrrole series were obtained with yields of 36-90percent from the oximes of alkyl aryl ketones by the Trofimov reaction.When vinyl chloride was used instead of acetylene under the same conditions (potassium hydroxide-DMSO, 80-100 deg C), the pyrroles were obtained with yields of 2-7percent.
