BIS(2,2,2-TRICHLORO-1,1-DIMETHYLETHYL) PHOSPHOROCHLORIDATE Chemische Eigenschaften,Einsatz,Produktion Methoden

Verwenden

BIS(2,2,2-TRICHLORO-1,1-DIMETHYLETHYL) PHOSPHOROCHLORIDATE is used as a phosphorylating reagent.

Synthese

Bis(2,2,2-trichloro-1,1-dimethylethyl) Phosphorochloridate is conveniently prepared by the reaction of 2-trichloromethyl-2-propanol with PCl3 in pyridine solvent to afford bis(2,2,2-trichloro-1,1-dimethylethyl) chlorophosphite (71%). The chlorophosphite is oxidized with (Diacetoxyiodo)benzene to give 65% of the desired phosphorochloridate (eq 1). This overall procedure represents an improved synthesis of the phosphorochloridate when compared to the different methods reported in the literature, which give mixtures of bis(2,2,2-trichloro-1,1-dimethylethyl) chlorophosphite and 2,2,2-trichloro-1,1-dimethylethyl dichlorophosphite.^[1][2]
