Abstract
A thionitrosoarene generated by the desulfurization reaction of a stab le N-thiosulfinylaniline bearing a bowl-type substituent underwent the intramolecular cyclization reaction involving the ortho-alkyl group t o afford the corresponding 3,3a-dihydro-2, 1-benzisothiazole, The inte rmediacy of the thionitrosoarene was corroborated by a trapping experi ment with aniline.
