(Chemical Equation Presented) Remove contents from tin ... Thiol esters have been successfully synthesized through tin-free radical carbonylation (see scheme; V-40 = initiator). This approach can be further extended to sequential radical reactions involving cyclization, carbonylation, and trapping of acyl radicals by phenyl benzenethiosulfonate.

Desulfurizations of saturated aliphatic or aromatic sulfoxides or sulfones are efficiently performed with nickel complex reducing agents (NiCRA's).The complete desulfurization of dithioketals can be effected in high yields with these reagents, while their half-desulfurization is efficiently achieved with 2,2'-bipyridine-modified nickel complex reducing agents (NiCRA-bpy).The desulfurization of vinyl thioethers, sulfoxides, and sulfones have been shown to be chemoselective, leaving the C-C double bond intact.The desulfurization of (E)-PhSO2(CH3)C=CHPh to cis-CH3CH=CHPh with NiCRA in the presence of quinoline is 95percent enantioselective.
