Abstract

Abstract Under comparable conditions, the isomerisation of 1, 1, 2-trichlorotrifluoroethane (I) to 1, 1, 1-trichlorotrifluoroethane (II) is more difficult than the isomerisation of 1, 2- difluorotetrachloroethane (III) to 1, 1-difluorotetrachloroethane (IV). Advantageously, III was isomerised to IV in the presence of I or II. The degree of isomerisation of the starting compounds I and III was 95-99%, the preparative yield of IV being 65-74%. The CF bond ...
