The reaction of oximes of aromatic ketones with phenylacetylene in the presence of superbase systems (MOH-DMSO, where M = Li, Na, K) has been extensively studied for the first time. The effects of alkaline metal cation, the ketoximes structure and the reaction conditions (temperature, duration) on the products composition have been evaluated. Acetophenone oxime reacts with phenylacetylene (МОН-DMSO, where M = Li, Na, K, 140 о С, 6 h) to afford 2,5diphenyl-1H-pyrrole in 14-18% isolated yield. The reaction of benzylphenylketoxime with phenylacetylene (LiОН-DМSО, 120 о С, 12 h) delivers 2,3,4-, 2,3,5-triphenyl-1H-pyrroles (in 17% total yield) and 2,3,4-triphenyl-1-[(Z)-2-phenylethenyl]-1H-pyrrole (7% yield).
