A series of chlorofluoroalkanes having chlorines on adjacent carbon atoms has been prepared, i.e. n-C5F11CFClCCl3, n-C6F13CFClCCl3, n-C5F11CFClCFCl2, n-C6F13CFClCFCl2, n-C5F11CFClCF2Cl, n-C2F5CFClCFClC3F7 and n-CF3CFClCFClC4F9, by a combination of halogen exchange, dehalogenation and chlorine addition reactions.An attempt to synthesize n-C6F13CFClCF2CFCl2 by the coupling of n-C6F13CFClI with an excess of ICF2CFCl2 under UV radiation in the presence of Hg gave only n-C6F13CFClCFClC6F13 together with CFCl2CF2CF2CFCl2.Under parallel conditions from n-C6F13CFClI and CF2ClCFClI, n-C6F13CFClCFClCF2Cl was obtained in 48percent yield.
