Abstract
In the liquidphase a specific and attractive intermolecular interaction exists between iodoor bromo-perfluoroalkanes (Rf - X, Rf = perfluorinated chain, X = Br, I) and heteroatomcontaininghydrocarbons (El) and it is robust enough to overcome the low affinity between perfluorocarbons and hydrocarbons. The interaction results in the formation of Rf - X····El complexes and this formation strongly affects 14N and 19F NMR spectra of the partners. An association constant of 10.7 ± 1 mol−1 has been determined.Pubblicazioni consigliate
