✦ Synopsis
Three Component Reactions. XIV. 2‐Imidazolines and 1,2,4‐Triazoles by Ring Closure Reactions of N‐(2‐Chloro‐alkyl)imidchlorides with Hydrazine and Hydrazones
N‐(2‐Chloro‐alkyl)benzimidchlorides (1a and 1b) give with hydrazine in dependence on the reaction medium 1,1′‐bis(2‐imidazolines) (4), 1‐benzamido‐2‐imidazolines (5) or 1,2,4‐triazoles (6 and 7) and also N‐(2‐chloro‐alkyl)benzamides (8). From imidchlorides (1a–c) and hydrazones Schiff bases (10) of 1‐amino‐2‐imidazolines are obtained. They are not cleavable into free 1‐amino‐2‐imidazolines. magnified image
