Pyrroles from Ketoximes and Acetylene. 42. Features of the Synthesis of New 2-Arylpyrroles
The respective 2-aryl- and N-vinyl-2-arylpyrroles were obtained by the reaction of the oximes of alkyl aryl ketones with acetylene in the superbasic medium MOH (M = Li, K)-DMSO.Their yields depended largely on the structure of the ketoximes and on the reaction conditions.

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.
