Addition of the carbanion of chloromethylphenylsulfoxide 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.
A facile and efficient protocol for the α-benzoyloxylation of β-keto sulfides is presented. This methodology provides a step-economical, mild and practical access to highly functionalized α-O-benzoyloxy substituted β-keto sulfides, including those with quaternary carbons, which are not easily obtained through currently available methods.

Chemoselective Method for the Preparation of Phenyl Sulfoxides by the Oxidation of Phenyl Sulfides with 2-Hydroperoxy-2-methoxypropane Phenyl sulfoxides are easily prepared by the chemoselective oxidation of the corresponding sulfides with molecular equivalents of 2-hydroperoxy-2-methoxypropane. This reagent is generated from 2,3-dimethyl-2-butene by ozonization in methanol.
