iodosylbenzene promoted oxidation of a number of α-alkylbenzyl alcohols catalysed by 5,10,15,20-tetrakis(pentafluorophenyl)porphyrin iron(III) chloride (Fe(III)TPFPPCl) leads to the formation of CH and CC bond cleavage products, aryl ketonesand benzaldehydes, respectively. It is suggested that the CH bond cleavage path occurs through a hydrogen atom transfer (HAT) mechanism, whereas CC bond cleavage products
5,5,10,15,20-四(五氟苯基)卟啉三氯化铁(Fe(III)TPFPPC1)催化的碘代乙苯促进了许多α-烷基苄醇的氧化导致CH和C的形成C键裂解产物,芳基酮和苯甲醛。建议通过氢原子转移(HAT)机理发生CH键的裂解路径,而CC键的裂解产物则来自铁氧代配合物和醇之间形成的中间配合物的分解。
