全氟-2,3,3,4-四甲基戊烷 | perfluoro-2,3,3,4-tetramethylpentane | 120615-52-3 | C9F20 | 488.067 |
CO2 laser-induced homogeneous decomposition of i-C3F7I yields a variety of perfluorinated compounds, which are suggested to be formed by recombinations of carbenes and radicals generated upon the cleavage of the C-I bond and the fragmentation of the i-C3F7
Coupling reactions of chlorofluoro- and perfluoroalkyl iodides Rf-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.
