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.

unactivated C(sp3)–H bonds and aliphatic carboxylic acids. The process is enabled by the trapping of alkyl radicals generated through hydrogenatomabstraction by arylsulfonyl-based SOMO-philes, which introduces a large array of C, N, S, Se, and halide-based functional groups. The chemoselectivity can be switched from C–H functionalization to decarboxylative functionalization by matching the bond dissociation
