Clarification on the Reactivity of Diaryl Diselenides toward Hexacyclohexyldilead under Light

In this study, the reactivity of organochalcogen compounds toward a representative alkyl-lead bond compound under light was investigated in detail. Under light irradiation, the Cy-Pb bond of Cy Pb (Cy = cyclohexyl) undergoes homolytic cleavage to generate a cyclohexyl radical (Cy•). This radical can be successfully captured by diphenyl diselenide, which exhibits excellent carbon-radical-capturing ability. In the case of (PhS) and (PhTe) , the yields of the corresponding cyclohexyl sulfides and tellurides were lower than that of (PhSe) . This probably occurred due to the low carbon-radical-capturing ability of (PhS) and the high photosensitivity of the cyclohexyl-tellurium bond.
