hydrophosphinylation of α‐acyl‐α‐diazoacetates with hydrophosphoryl compounds is developed through the generation of (diazomethyl)ketones and the subsequent C–P coupling. The findings imply the potential use of the relatively more readily available α‐acyl‐α‐diazoacetates as replacement of (diazomethyl)ketones in some cases.

alpha-diazo-beta-ketoesters can be prepared in good overall yields via a two-step sequence involving addition of ethyl lithiodiazoacetate to aliphatic, aromatic and conjugated aldehydes followed by mildoxidation with the Dess-Martin periodinane.
