Chlorofluoroalkyl radical rearrangements mediated by electron donors. An e.s.r. study in freon matrices
Abstract
E.s.r. studies reveal that the CF2ClĊFCl radical ordinarily produced in γ-irradiated CF2ClCFCl2 solid solutions can rearrange to CF3ĊCl2 in the presence of amines with low ionization potentials, suggesting that this unexpected radical isomerization proceeds through chlorofluoroalkyl carbanionic species formed reversibly by electron transfer.
