Equimolar reactions of sulfenamides derived from secondary alkylamines with active methylene compounds afforded mono-sulfenylated compounds in good yields. The reactions of 2 mol of sulfenamides derived from imides with 1 mol of active methylene compounds in the presence of a base gave di-sulfenylated compounds. It was found that α- mono-sulfenylated ketones were prepared by the reactions of enamines with ...
