Dimethylglyoxime reacts with acetylene under pressure in the KOH-DMSO system to give 1-vinyl-2-[2′-(6′-methylpyridyl)]pyrrole along with the expected products of the Trofimov reaction (O-vinyloxime, pyrrole and dipyrrole).

3,3′-Dimethyl-1,1′-divinyl-2,2′-dipyrrole was obtained during the reaction of 3,4-hexanedione dioximes with acetylene under pressure in the potassium hydroxide-DMSO system. In the case of 1,2-cyclohexanedione dioxime 2,2′-dipyrrole and 2-pyridyl- and 2-acylpyrroles were isolated. α-Benzil and α-furil dioximes give 3,4-diphenyl- and 3,4-di(2-furyl)-1,2,5-oxadiazoles respectively in addition to their mono- and divinyl derivatives. 2006 Springer Science+Business Media, Inc.
