α-Sulfinyl carbenoid: One-carbon homologation of ketones to α-sulfinyl ketones using chloromethyl phenyl sulfoxide

Article abstract of DOI:10.1016/S0040-4039(00)60867-5

Addition of the carbanion of chloromethyl phenyl sulfoxide to ketones gave the adducts, which were treated with lithium diisopropylamide to afford one-carbon homologated α-sulfinyl ketones via α-sulfinyl carbenoids in moderate to high yields.
