Abstract

1. From the higher perfluorodicarboxylic acids of the general formula HOOC(CF2)nCOOH, where n is 4,8,12, which are prepared from the products of the telomerization of tetrafluoroethylene with trifluoridchloroiodoethane, difunctional derivatives have been synthesized — acid chlorides, esters, amides, nitriles, and amidines. 2. By reduction of the esters of perfluoroadipic, perfluorosebacic, and perfluorododecamethylenedicarboxylic acids with sodium borohydride in the presence of anhydrous aluminium chloride, the corresponding α,α,ω,ω-tetrahydroperfluorodiols with the general formula, HOCH2(CF2)nCH2OH(n=4,8,12) have been obtained.
