摘要

Thermolysis of 2-phenoxybenzenesulfonyl azide gave 6H-dibenzo [b, f][1, 4, 5] oxathiazepine 5, 5-oxide (4)(the first seven-membered ring compound formed by intramolecular aromatic cyclization of a sulfonylnitrene) and other nitrene-derived products. On the other hand, diphenyl sulfide 2-sulfonyl azide (lb) gave some 3-phenylbenzo [l, 3, 2]- dithiazolium ylide 1, l-dioxide (lo), but no seven-membered ring compound. Thermolysis of ...
