The interaction between perfluoroorgano iodides (R_fI where R_f = F(CF3)2C(CF2CF2)3, n-C6F13, n-C8F17, F(CF3)2COCF2CF2, F(CF3)2CO(CF2CF2)4 and C2H5OC(O)(CF2CF2)2OCF2CF2) with cadmium in an acetonitrile solvent media produces primarily the coupled products (R_fR_f, 72-90percent yield) in addition to minor quantities of the reduction products (R_fH).On the other hand ICF2CF2I and ClCF2CFClI, by a 1,2-dehalogenation reaction, from the olefins CF2=CF2 and CF2=CFCl, respectively, as the principal products.The interaction of R_fI compounds with cadmium in other solvent media, e.g. diethyl ether, tetrahydrofuran (YHF)), N,N-dimethylformamide (DMF), and bis(2-methoxyethyl)ether(diglyme) were examined and found to produce a different ratio of R_fR_f and R_fH products.
