Sodium dialkylphosphite reacts with trichlorovinylbenzene to yield in an one-batch procedure 1-phenyl-1,2,2-ethanetriphosphonic acid hexaalkyl esters.A carbanionic intermediate of an "anomalous Michaelis-Becker reaction" is deduced.Acidolysis of esters leads to the parent triphosphonic acids.NMR parameters of this acid are strongly influenced by protolytic equilibrium. - Key words: One-batch synthesis, Oligophosphonic Acid, NMR Spectra
