Perkin communications. An e.s.r. study of radical cation cyclization in the radiolytic oxidation of but-3-en-1-ol solutions in Freon matrices

Abstract

The radiolytic oxidation of but-3-en-1-ol in halogenoethane matrices produces e.s.r. signals from both the protonated tetrahydrofuran-3-yl radical and the ally radical; the former species is readily attributable to the nucleophilic endo cyclization of radical cations generated from unassociated solute molecules whilst the ally radical is thought to originate from the fragmentation of the alkoxyl radical produced from radical cations generated within solute clusters.
