Preparation of first examples of RFCCIF4 molecules. A study of the fluorination of selected 1-iodoalk-1-ynes with xenon difluoride/boron trifluoride

First examples of alk-1-yn-1-yliodine(V) molecules, CF3CCIF 4 and C6F13CCIF4, were prepared by fluorination of the corresponding 1-iodoperfluoroalk-1-ynes with XeF2 in 1,1,1,3,3-pentafluoro

Experimental and theoretical studies on the reactivities of partially and fully fluorinated primary alkyl radicals

Absolute rate constants for hydrogen abstraction from n-Bu3SnH by a number of partially-fluorinated and fully fluorinated n-alkyl radicals have been measured. The C-H and C-C bond dissociation energies for a number of pertinent hydrofluorocarbons have been calculated by DFT. The rate data are compared with those for addition of the same radicals to styrene, and the reactivities of these radicals are discussed in terms of their electronegativies, their structure and the thermodynamics of their reactions.

Poly-4-vinylpyridinium poly(hydrogen fluoride): A solid hydrogen fluoride equivalent reagent

Poly-4-vinylpyridinium poly(hydrogen fluoride) (PVPHF), containing 35-60% hydrogen fluoride by weight, was prepared as a solid hydrogen fluoride equivalent reagent. PVPHF with 60% hydrogen fluoride by weight was found to be a versatile fluorinating agent for the hydrofluorination and bromofluorination of alkanes and alkynes, fluorination of alcohols as well as other fluorination reactions. Low hydrogen fluoride content PVPHF (3 equivalents of hydrogen fluoride to 1 equivalent of 4-vinylpyridine unit) was also found to be an efficient reagent for bromofluorination of alkenes in the presence of 1,3-dibromo-5,5-dimethylhydrantoin. Fluorosulfonic acid-modified PVPHF showed enhanced reactivities for the fluorination of secondary alcohols.
