Abstract
2-Tributylstannyl-1, 3-dithianes and 1-(tributylstannyl) alkyl sulfides are oxidized with ammonium hexanitratocerate (IV) or ferrocenium hexafluorophosphate to generate their cation radicals, which dissociate into the carbocations and tributylstannyl radical. The carbocations thus generated react with olefinic nucleophiles to afford the corresponding addition products in good yield.
