Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The principal tendencies of the effect of the nature of the cation of the hydroxide (Li+, Na+, K+, Rb+, Cs+), the solvent [DMSO, hexamethylphosphoric triamide (HMPT), 1-methyl-2-pyrrolidone, sulfolane, DMF, polyethylene glycol, hydrazine hydrate, tetramethylurea], and the additive (cesium and rubidium salts and linear and macrocyclic polyethers) in the KOH-DMSO catalytic system on the processes involved in the pyrrolization of acetophenone oxime with acetylene and the vinylation of the resulting 2-phenylpyrrole were ascertained.
