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

AN IMPROVED CONVERSION OF 1,4,6-TRISUBSTITUTED 2(1H)-PYRIMIDINONES INTO THE CORRESPONDING THIONES

1,4,6-Trisubstituted 2(1H)-pyrimidinones (2a-j) are easily converted into the corresponding thiones (3a-j) in high yields by reacting with 2,4-bis(p-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide (1).Further, other diazines, e.g., 2-methyl-6-phe
