"Process for the preparation of esters of thio- or dithiophosphoric acid (-phosphonic acid, -phosphinic acid) characterized in that 0.0-dialkyl- (thiol) phosphoric acid or alkyl- (thiol) -0-alkylphosphonic acid ester or dialkyl- (thiol) phosphines are reacted with halides of 2-amido- or 2-N-alkyl- or 2-N, N-dialkylolamidocarboxy-phenylsulfenic acid, which in the phenyl radical are optionally substituted by halogen atoms, nitro groups or of low alkyl, or because the aforementioned (thiol) phosphoric acid - (- phosphonic) ester thiol (phosphinic) acids are first reacted with 2-halogeno-carboxy-phenylsulfenic acid halides and then -conveniently without isolation of the intermediates- with ammonia, N-alkyl amines or N, N-dialkyl amines.
