Acyl-substituted methyl radicals (RCOCH2.; R = H, Me, Ph), generated by photolysis of RCOCH2-HgCl, add to alkenes, enol ethers, or vinyl sulfides to give adduct radicals that are readily trapped by PhSSPh to yield a three-component condensation product. The presence of an alkali metal carbonate is crucial in preventing side reactions resulting in the conversion of the mercurial to RCOCH3 by PhSH formed in the photolysis.
