The reaction of 1-phenylmethyl-4N-acetylimino-1H-1,2,4-triazolium betain with butynedioic acid dimethyl ester

The reaction between 1-phenylmethyl-4N-acetylimino-1H-1,2,4-triazolium betain(I) and dimethyl butynedioate is described.By performing the reaction at ration 1:1 the enamide III is formed.With a fivefold excess of the dipolarophile, except III, also pyrrolo-triazole XII and pyridine derivative XV were obtained.
