The 2,1-Benzisothiazolo-2,1-benzisothiazole System, Synthesis and Properties

2,2'-Diaminodiphenylmethane and its 4,4'-dibromo-derivative both react with N-sulfinylmethanesulfonamide to form 2,1-benzisothiazole derivatives.Methylation or acetylation of these provides examples of the hypervalent sulfur 2,1-benzisothiazolo-2,1-benzisothiazole system.The nmr spectra of these compounds are discussed.
