Nonactivated alcohols along with arene compounds are used in electrochemical dehydroxylative arylation for constructing C(sp3)–C(sp2) bonds. The PIII reagent undergoes single-electron anodic oxidation to form its radical cation, which reacts with the alcohol to produce an alkoxytriphenylphosphine radical. Through spontaneous β-scission of the phosphoranyl radical, the C–O bond is cleaved to form an
非活化醇与芳烃化合物一起用于电化学脱羟基芳基化以构建 C(sp 3 )–C(sp 2 ) 键。P III试剂经过单电子阳极氧化形成其自由基阳离子,该阳离子与醇反应生成烷氧基三苯基膦自由基。通过磷酰基自由基的自发β-断裂,C-O键裂解形成烷基自由基物质,其与贫电子芳烃阴极还原产生的自由基阴离子偶联,得到脱羟基芳基化产物。
