Condensation of diethyl phosphite with aldehydes followed by subsequent sulfonylation of the resulting hydroxy group formed with mesyl chloride gave the corresponding 1-sulfonyloxyalkylphosphonates, which led to the convenient synthesis of 1-hydrazinoalkylphosphonates via nucleophilic substitution by hydrazine. The products could be converted to the corresponding 1-hydrazinoalkylphosphonic acids by acid hydrolysis in high yield.
