Abstract

Abstract An efficient one-pot synthesis of the title compound 5 starting from methyl phenyl sulfoximine is described. On attempted iododesilylation of this compound using iodine chloride, one methyl group on the silicon atom is formally replaced by the imino nitrogen to give a derivative 8 of the novel heterocyclic system 1, 3, 2-benzothiasilazole. Keywords: Silylation, imination, demethylation, silyl migration, oxidative ring closure
