Treatment of sec-alkyl phenyl tellurides, except for the cyclohexyl system, with m-chloroperbenzoic acid(MCPBA) in diethyl ether readily afforded the corresponding olefins in good yields presumably via telluroxide elimination together with small amounts of alcohols and ketones. In the pri-alkyl and cyclohexyl cases the adducts between MCPBA and the tellurides were isolated as stable organotellurium(IV)
用间氯过苯甲酸(MCPBA)在乙醚中处理除环己基体系以外的仲烷基苯基碲化物,大概可以通过消除碲氧化物和少量的醇和酮轻松获得高收率的相应烯烃。在pri-烷基和环己基的情况下,MCPBA和碲化物之间的加合物被分离为稳定的有机碲(IV)化合物,通过在220–2500°C下进行纯热解可得到相似的消除产物。
