Addition of the carbanion of chloromethylaryl sulfoxide to aldehyde gave the adduct, which was treated with three-equivalents of lithium diisopropylamide (LDA) to afford β-keto sulfoxide in high overall yield.

A two-step and high-yield method for the synthesis of α-thio aldehydesfromaldehydes with one-carbon elongation is realized by using chloromethyl phenyl sulfoxide as a one-carbon homologating agent. The α-thio aldehydes are easily converted to desulfurized alcohols with Bu3SnH and AIBN in refluxing benzene in good yield.

1-Chlorovinyl sulfoxides, easily prepared from aldehydes and chloromethyl phenyl sulfoxides, were treated with t-butyllithium to afford one-carbon homologated acetylenes via alkylidene carbenoids in high yields.
