can in situ generate arylsulfenyl radicals. These radicals have high reactivity to react with alkynes, alkenes, and H-phosphine oxides for the synthesis of alkyl and alkenyl sulfides and phosphonothioates. The control experiments and quantum calculations are also performed to gain insights into the generation mechanism of arylsulfenyl radicals. Notably, the chemistry is free of thiol odors, organic solvents
A new method for the preparation of alkyl aryl sulfides through direct oxidative thiolation of alkanes or ethers with arylsulfonylhydrazides using di-tert-butyl peroxide (DTBP) as an oxidant catalyzed by Pd(OAc)2 has been reported. The C-H bonds in various alkanes or ethers were successfully converted into C-S bonds to yield the corresponding sulfides in moderate to good yields.
