In this paper, a visible-light-promoted cross-coupling of 4-alkyl-1,4-dihydropyridines with thio-/selenium sulfonates under transition-metal-free conditions is described. This strategy features easily available substrates, mild reaction conditions, high yields, and high chemoselectivity. A novel synthetic route for the construction of a sulfide or selenide Csp3-S or Csp3-Se bond under transition-metal-free conditions without an additive oxidant or base is developed. This method is well extended to the synthesis of a class of thiolated or selenylated glycosides that has not been explored before. Sulfoxides were also successfully chemoselectively observed via a facile variation of the atmosphere under photocatalyzed conditions.

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.
