we devised a phosphorus-containing species as a radical precursor, but without the generation of phosphorus waste. Accordingly, a catalyst-free synthesis of phosphinic amides from hydroxyl amines and chlorophosphines via P(III) to P(V) rearrangement is described. Mechanistically, it may involve the initial formation of a R2N–O–PR2 species that undergoes homolysis of N–O bonds and subsequent radical
膦酰基是产生新自由基的重要介质,但通常会产生化学计量的氧化膦/硫化物废物。在此,我们设计了一种含磷物质作为自由基前体,但不会产生磷废物。因此,描述了通过 P(III) 到 P(V) 重排从羟基胺和氯膦无催化剂合成次膦酰胺。从机理上讲,它可能涉及 R 2 N–O–PR 2物种的初始形成,该物种经历 N–O 键的均裂和随后的自由基重组。
