Organic Synthesis and Industrial Organic Chemistry


2-Pentafluorophenyl-2-trifluoromethyl-1,3-dioxolane was prepared by cyclization of octafluoroacetophenone with 2-chloroethanol under the conditions of base catalysis. Successive chlorination of the product yielded the corresponding 4,4,5,5-tetrachloro derivative. Fluorination of the latter in the SbF3/SbCl5 system yields 4,5-dichloro-4,5-difluoro-2-pentafluorophenyl-2-trifluoromethyl-1,3-dioxolane.
