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 Cy6Pb2 (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
在这项研究中,详细研究了有机硫属化合物在光下与代表性烷基铅键化合物的反应性。在光照射下,Cy 6 Pb 2 (Cy=环己基)的Cy-Pb键发生均裂,生成环己基自由基(Cy•)。该自由基可以被二苯基二硒化物成功捕获,表现出优异的碳自由基捕获能力。在(PhS) 2和(PhTe) 2的情况下,相应的环己基硫醚和碲化物的产率低于(PhSe) 2的产率。这可能是由于(PhS) 2的低碳自由基捕获能力和环己基碲键的高光敏性而发生的。
