A metal-free, photocatalyst-free, photochemical system was developed for the direct alkylation of thiophenols via electron donor-acceptor (EDA) complexes (KEDA = 145 M-1) between two reactants, N-hydroxyphthalimide esters as acceptors and thiophenol anions as donors, in the presence of a tertiary amine. The EDA complexes in the reaction system have a broad range of visible-light absorption (400-650 nm) and can trigger the reaction effectively under sunlight.

A study on the coupling of cycloalkanes with alkyl arylsulfinates has been performed. Using iodine as the catalyst, through C (Formula presented.) ?H bond activation and sulfinates reduction, a wide range of thioethers were produced in moderate to high yields. Additionally, various thiocarboxylic esters can also be produced by simply performing the reaction under CO pressure. Notably, this is the first report in which alkyl arylsulfinates were used as sulfenylation agents in a cross-coupling transformation.

A new protocol for C-S and C-Se bond formation by the direct functionalization of the C(sp3)-H bond of alkanes under metal-free conditions was developed. Using tBuOOtBu as the oxidant, the reaction of disulfides or diselenides with alkanes gave sulfides or selenides in moderate to good yields. The method was very simple and atom-economical.

A new method for the preparation of alkyl aryl sulfides through direct oxidative thiolation of alkanes or ethers with arylsulfonyl hydrazides 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. the Partner Organisations 2014.
