hydrothiocarbonylation of unsaturated carbon–carbon bonds at room temperature with high chemo- and regioselectivity. The reaction is applicable to the synthesis of cysteine-derived thioesters, thus allowing chemical modification of cysteine-containing peptides. Decarboxylation of OAM proceeds through oxidative addition of Pd(0) to the acyl–S bond, which accounts for the very mild reaction conditions

A novel, efficient, and catalyst-free strategy has been initially developed for the construction of thioesters via the direct radical oxidative decarboxylation of α-ketoacids with thiols, and the corresponding target products were obtained in moderate to good yields. It offers an alternative approach for the synthesis of useful diverse thioesters.

A DTBP-promoted, operationally simple, metal-free and solvent-free formation of C–Se and C–S bonds through sp3C–H functionalization of methyl arenes with diselenides and disulfides is described.
Zeolite Beta nanoparticles assembled Cu catalysts with superior catalytic performances in the synthesis of thioesters by cross-coupling of aldehydes and disulfides
Development of the highly active and stable heterogeneous transition metal catalysts is of great importance in synthetic chemistry. Herein, zeolite Beta nanoparticlesassembled Cu catalyst (Cu-Beta-Nano) with high external surface area was directly synthesized, and it exhibits excellent catalytic activity and good recyclability in cross-coupling of aldehydes and disulfides for synthesis of thioesters
