Coupling reactions of chlorofluoro and perfluoroalkyl iodides
Coupling reactions of chlorofluoro- and perfluoroalkyl iodides R f-I with Rf = ClCF2CFCl-(CF2) 3CF2-, ClCF2CFClO(CF2) 3CF2-, ClCF2CFCl-, (CF3) 2CF- , (CF3)2CFCF2CF2- in the presence of a zinc/solvent system give dimers in good yields. Both homodimerizations (one iodide) and heterodimerizations (two different iodides) have been studied. The effect of temperature and solvent is shown. The zinc mediated dechlorination of vicinal chlorine atoms in the dimers afforded terminal alkenes and dienes.
