Synthesis of 2-Phosphono Alkyl 1,2-Benzisoselenazol-3(2H)-ones
摘要:
A series of 2-phosphonoalkyl 1,2-benzisoselenazol-3(2H)-ones were designed and synthesized via reaction 2-chloroselenobenzoyl chloride with 1-hydrazinobenzyl phosphonate. The structures of all new compounds were confirmed by spectroscopic methods and microanalyses.

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.
