Several 4,5-diamino-4,5-dihydroimidazoles, 1, have been synthesized in order to study the effects of the substituents in the imidazole ring on the rearrangement to N-(1,2-diaminoethylidene)amidine, 2.The rate of the process increases with the increase in

During the preparation of 1-aryl- and 1-acyl-4,5-dipiperidino-4,5-dihydroimidazoles (1) from diimmonium salts (3), derivatives in which one of the piperidino groups was substituted by an hydroxy group were often isolated.The structure and the genesis of t
