HOE 90/F 201 Novel aryl esters of phosphonous halides and a process for the preparation thereof. Aryl esters of phosphonous halides of the formula I (I) in which R1 is a phenyl or benzyl radical which bears 1 to 3 substituents, methylbenzyl, .alpha...alpha.-dimethylbenzyl, naphthyl or a naphthyl radical bearing 1 to 5 substituents, where the substituents are identical or different and are a non-aromatic hydrocarbon radical, an alkoxy radical or alkylthio radical each having 1 to 8 carbon atoms, aryl or aryloxy each having 6 to 10 carbon atoms or halogen having an atomic number from 9 to 35, R2 is a non-aromatic hydrocarbon radical having 1 to 18 carbon atoms, aryl, arylmethyl, arylethyl or arylisopropyl, where each aryl contains 6 to 1 carbon atoms, R3 is hydrogen or one of the groups mentioned under R2, and X is chlorine or bromine. The invention further relates to a process for the preparation of aryl esters of phosphonous halides of the formula I.
