Tautomerism in 6-Arylpyridazin-3(2H)-thiones and Some of Their Reactions

6-Arylpyridazin-3(2H)-thiones exist mainly, if not entirely, in the thione form (1).This was shown by spectroscopic studies on some of these compounds and their substitution products either on the nitrogen or on the sulphur in the mercaptopyridazine form

SYNTHESE D'ACYL-ALKYLIDENE-3 DIHYDROPYRIDAZINES PAR UNE REACTION D'EXTRUSION DE SOUFRE

Des acyl-alkylidene-3 dihydropyridazines sont obtenues par une reaction mettant en jeu l'extrusion du soufre des acyl-alkylthio-3 pyridazines N-alkylees correspondantes.Cette reaction d'extrusion n'a pas lieu sur des cycles pyridaziniques non alkyles sur
