2,2′‐Diaminodiphenylmethane and its 4,4′‐dibromo‐derivative both react with N ‐sulfinylmethanesulfon‐amide to form 2,1‐benzisothiazole derivatives. Methylation or acetylation of these provides examples of the hypervalent sulfur 2,1‐benzisothiazolo[2,3‐ b ]‐2,1‐benzisothiazole system. The nmr spectra of these compounds are discussed.
