使用Diethyl (trichloromethyl)phosphonate may be used in the synthesis of chlorovinyl phosphonates via reaction with aldehydes and ketones.
一般的な説明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.
製造方法Diethyl trichloromethylphosphonate was also obtained from diethyltrimethylsilyl phosphite in 60 % yield, and from benzyldiethyl phosphite in the presence of dibenzoyl peroxide and an ultraviolet source in a radical induced reaction in 87 % yield (compared to 26 % without the dibenzoyl peroxide).
