The research was focused on the defluorination of chlorofluoroethers to corresponding esters using porous aluminum fluoride (PAF) or MFn/PAF. In the work up process, the product was easily separated from the reagent. Thus, the reaction would be a practical preparation method for polyfluorinated esters. Trifluoromethyl chlorodifluoroacetate was obtained by the reaction of 1,2-dichlorotrifluoroethyltrifluoromethyl ether with fuming sulfuric acid in 49% yield.

, p. 65 - 69 (2007/10/03)
A novel material, porous calcium fluoride (PCF) with more than 60m2/g surface area, was prepared by the reaction of soda lime (SL) with anhydrous hydrogen fluoride (AHF), and its application as a fluorinating reagent and support of catalyst was investigated.

, p. 145 - 148 (2007/10/03)
Reaction of 1,2-dichloro-1,1,2-trifluoro-2-methoxyethane with anhydrous hydrogen fluoride (AHF) was investigated in the presence of metal fluorides supported on porous aluminum fluoride (PAF). 2-Chloro-1,1,2,2-tetrafluoro-2-methoxyethane, a new compound,
