The reaction of trialkyl phosphites, dialkyl phenylphosphonites or alkyl diphenylphosphinites with N-alkylalkanimines in the presence of hydrogen chloride gives dialkyl 1-(alkylamino)alkylphosphonates, alkyl amino)alkyl]phenylphosphinates or [1-(alkylamino)alkyl]diphenylphosphine oxides respectively, via Arbusov-like reaction of iminium salts generated in situ from N-alkylalkanimines. This reaction is an alternative and competitive to known method of preparation based on the addition of H-P compounds to N-alkylalkanimines, because it gives higher yields, no heating is necessary, and the isolation of products is easy.
