Description

General description

Addition reaction of diethyl (trichloromethyl)phosphonate to olefins by non-chain catalytic reactions catalyzed by copper amine complexes has been reported. Irradiation of diethyl (trichloromethyl)phosphonate in MeCN is reported to afford corresponding monoesters and olefins, via photochemical type II elimination reaction.

Application

Diethyl (trichloromethyl)phosphonate may be used in the synthesis of chlorovinyl phosphonates via reaction with aldehydes and ketones.
