Cyclic meso-ionic heterocycles. Part 24. The reaction of 1,2-dithiolium-4-olates with aniline. The formationof 11-phenylbenz[b]indeno[2,1-e]-1,4-thiazine
摘要:
Reaction of the type B meso-ionic heterocycle 3,5-diphenyl-1,2-dithiolium-4-olate (1) with aniline yields N-phenyl-(3-phenyl-1-phenylimino-inden-2-yl)-amine (10) and 11-phenylbenz[b]indeno[2,1-e]-1,4-thiazine (12). Mechanistic investigations establish that the 3-phenylindenylamine (10) is an intermediate in the formation of the tetracyclic 1,4-thiazine (12).
