The reaction with chloral of 2-[1-(3-chlorophenyl)-2,2,2-trifluoroethoxy]-5,6-benzo-1,3,2-dioxaphosphorinan-4-one containing a chiral fluorinated exocyclic substituent on phosphorus leads to formation of 2-[1-(3-chlorophenyl)-2,2,2-trifluoroethoxy]-3-(trichloromethyl)-6,7-benzo-1,4,2l 5 -dioxaphosphepin-5-one 2-oxide with a high regio-and stereoselectivity. The molecular and supramolecular structure of the isolated diastereomer was established by means of X-ray diffraction.
