Simple and improved preparation of α-oxophosphonate monolithium salts

Wang, Tao,Hong, Wu He

, p. 2081 - 2089 (2007/10/03)

Some α-OxoPhosphonate monolithium salts were synthesized by a facile one-step procedure. In this way, α-(2,4-dichlorophenoxyacetoxy)alkyl phosphonic acid dimethyl esters 5 can be transformed into the corresponding phosophonate monolithium salts 6 without influence on the carboxylic ester group under mild conditions.
