Seven low-molecular weight perfluoroalkylethers have been subjected to thermal degradation using a flow pyrolyzer attached to a gas chromatograph, and the results are compared with thermal decomposition of two perfluoroalkanes. Both linear and branched ethers were studied. The major degradation products from the ethers were identified by GC/MS. Products due to specific C-O bond fission were detected from only two of the ethers. Hexafluoropropylene was the most prominent product from all the ethers studied. While the perfluoroalkylethers in general were more stable than perfluoroalkanes, linear ethers were more stable than branched ethers. The stability of the ethers also decreased with increasing number of adjacent C-C bonds.

The interaction between perfluoroorgano iodides (RfI where Rf = 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 (RfRf, 72-90percent yield) in addition to minor quantities of the reduction products (RfH).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 RfI 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 RfRf and RfH products.
