A new, practical, synthesis of β-ketophosphonates relying on the conversion of the organolithium reagentfrom a dialkyl methylphosphonate into the correspondingorganocopperreagent, and its reaction with acylchlorides is described. The structure of the intermediate organocopperreagents is discussed.

Allenic phosphonates, readily accessible from 1-alkin-3-ols, the addition products of 1-alkines to aldehydes or ketones, can be transformed to β-ketophosphonates by nucleophilic addition of diethylamine and subsequent hydrolysis of the formed enamines.
