the direct conversion of aldehydes to thioesters via integration of organocatalysis and electrosynthesis. The thiazolium precatalyst was found to facilitate oxidation of thiolate anions, leading to deleterious formation of disulfide byproducts. By circumventing this competing reaction, thioesters were obtained in good-to-excellent yields for a broad range of aldehyde and thiol substrates. This approach

The firstexample of catalytic thiocarbonylation of aryl iodides using CO2 has been achieved employing a combination of PdCl2 and carbazole-derived phosphine ligands. Under mild conditions, a broad scope of aryl iodides were converted to the desired thioester products in the presence of aryl or alkyl thiols (33 examples, up to 96% yields). The choice of metal, ligands, and reductant were crucial for
