A “one-pot” strategy for the straightforward Mn(III)-mediated phosphinoylation of aldehyde hydrazones with diphenylphosphine oxide to furnish α-iminophosphine oxides is described. This mild and practical method allows the direct use of aldehydes as substrates in one pot to generate the hydrazones, which are then engaged “in situ” by the phosphorus reagent in the presence of Mn(OAc)3 oxidant. Thus,
描述了一种简单的“一锅法”策略,该方法用于Mn(III)介导的醛与二苯基膦氧化物的直接膦酰基化,以提供α-亚氨基膦氧化物。这种温和而实用的方法允许在一个锅中直接使用醛作为底物来生成the,然后在Mn(OAc)3氧化剂存在下,磷试剂将其“原位”结合。因此,在该操作中不需要the的必要分离。进行的机械实验暗示了涉及以磷为中心的自由基的途径。
