ABSTRACT:
P,P-dihydrocarbylphosphinoacetic acids are prepared by reacting a 2-methyl-4,4-dialkyl-2-oxazoline (preferably 2,4,4-trimethyl-2-oxazoline) with a basic alkali metal compound (preferably potassium hydride), followed by coupling with at least one halodihydrocarbylphosphine (preferably chlorodiphenylphosphine or chlorodiethylphosphine or chlorodi(t-butyl)phosphine or chlorodicyclohexylphosphine), and subsequent hydrolysis under acidic conditions.
