Porous AlFm(OH)3-m was prepared by heating AlF3·3H2O. Methyl chlorodifluoroacetate was synthesized in 77% yield by the reaction of 1,2-dichloro-1,1,2-trifluoro-2-methoxyethane with AlFm(OH)3-m/s

An indirect and uncatalysed esterification of chlorodifluoroacetic acid with polyfluoro and hydrocarbon alcohols has been developed. The method which involves the reaction between sodium chlorodifluoroacetate and alcohols in dimethylformamide (DMF) is par
Defluorination of homologous chlorofluoroethers to chlorofluoroacetates

, p. 131 - 134 (2003)
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.

Producing compounds (I) with a mono- or difluoromethyl group from compounds (II) with a mono- or difluorohalomethyl group, where halo is bromo, iodo or preferably chloro, comprises reacting (II) with zinc in the presence of an alcohol. An independent claim is also included for an azeotropic mixture of methyl difluoroacetate and methanol.
