M. Takahashi et S. Yoshizawa, SYNTHESIS OF -ARYLAMINO-3-ARYLIMINO-1,2-DITHIOLE-4-SULFONAMIDES FROM METHANESULFONAMIDES AND ARYL ISOTHIOCYANATES, Heterocycles, 43(12), 1996, pp. 2733-2739
-Arylamino-3-arylimino-1,2-dithiole-4-sulfonamides were obtained in on
e pot by the reaction of methanesulfonamides with aryl isothiocyanates
in the presence of butyllithium followed by oxidation with hydrogen p
eroxide.
