The copper(II) triflate and chlorotrimethylsilane combination was found to be effective for the conjugate addition of α-sulfur-substituted alkylstannanes to α,β-unsaturated ketones. Thus, the corresponding γ-sulfur-substituted ketones were obtained in good yields.
Generation of<i>α</i>-Alkylthio Radicals by Photoinduced One-Electron Oxidation of<i>α</i>-Stannyl Sulfides and Their Use for Carbon-Carbon Bond Formation
Cation radicals, generated from α-stannyl sulfides by the photoinduced single electron transfer, cleave into α-alkylthio radical intermediates with the elimination of the stannyl group. The α-alkylthio radicals thus formed are utilized for carbon-carbon bond forming reactions.

Some sulfur-substituted organotin compounds, R3SnCH2X, where X = SCH3, SO2C4H9-n, SO2C6H5, S+(CH3)2Z−, etc., have been synthesized and studied with regard to their solvolytic and “organometallic-like” behavior. Reactions of the organotin compounds with substrates known to be reactive toward classical organometalliccompounds tend to place these materials by comparison on the lower end of the reactivity

generation of α‐thiomethyllithium reagents via reductive lithiation or deprotonation followed by reaction with variously functionalized Weinreb amides represents an excellent method to access β‐oxo thioethers. The procedure is adaptable to alkyl‐ or aryl‐ thiomethyllithium conjugates. It has the advantages of conceptual simplicity and versatility of the addition of organometallics to Weinreb amides with the
