| Diethyl (trichloromethyl)phosphonate Usage And Synthesis |
| Chemical Properties | Colorless to Almost colorless clear liquid. | | Uses | Diethyl (trichloromethyl)phosphonate may be used in the synthesis of chlorovinyl phosphonates via reaction with aldehydes and ketones. | | Preparation | 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). | | Application | Diethyl trichloromethylphosphonate has been used as a carbenoid precursor in the reaction with Bu3B.Diethyl trichloromethylphosphonate is used mainly in the synthesis of 1,1-dichloro-1-alkenes from carbonyl compounds via Horner–Wadsworth–Emmons (HWE)-type reactions.Diethyl trichloromethylphosphonate reacts with olefins under Cu(I) or Fe(III) catalysis to give insertion of the olefinic substrate into one of the C–Cl bonds. | | 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)phosphonatein MeCN is reported to afford corresponding monoesters and olefins, via photochemical type II elimination reaction. |
