Abstract:

The reaction of 1, 3-benzoxanin-4-one 1 and 1, 3-benzothiazin-4-thione (5) with alky, aralkyl and or aralky magnesium halides has been described. P2S5 reacted with (1) and yielded the corresponding benzothiazin-4-one (5). Primary amines condensed with (1) and (5) giving the corresponding Schiff's bases (7 a-d) or (8 a-d) respectively. Also I reacted with hydrazine hydrate and gave the triazole derivative (9). But (1) condensed with p-nitrophenyl hydrazine and hydroxyl amine and yielded the corresponding hydra- zone and oxime derivatives (10 a-b). On the other hand, compound (5) reacted with ammonia derivatives and gave the condensation products (11 a-d).
