The direct alkylsulfenylation of various activated C−H bonds has been reported. The reaction utilizes sulfonium salts as sulfenylation reagents which are readily prepared, operationally simple, and performe under mild reaction conditions.
The methanesulfenylation of various mercaptans and β-dicarbonyls has been investigated using in-situ generated methyl methanethiosulfonate (MMTS) from DMSO, facilitated by a catalytic amount of (CO...
