Synthesis of 2-Phosphono Alkyl 1,2-Benzisoselenazol-3(2H)-ones

Abstract

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.

Keywords:

• 1-Hydrazinobenzyl Phosphonate
