Shapiro, Robert H. published the artcileEvidence for anchimeric assistance in the expulsion of bromine from ring-substituted β-phenylethyl bromides: when is a simple cleavage a rearrangement, HPLC of Formula: 1997-80-4, the publication is Organic Mass Spectrometry (1969), 2(8), 771-80, database is CAplus.
Using the principles of the quasi-equilibrium theory, substituent effects, deuterium labeling, and comparison of compound behavior, evidence is given for aryl participation in the expulsion of Br from the mol. ion of β-phenylethyl bromide and eleven of its ring-substituted derivatives This reaction shows a kinetic behavior which is typical of rearrangements, its activation energy is lower than that of similar reactions where participation is partially or completely precluded and substituent effects are not only consistent with a participation process, but are also consistent with those predicted from solution chemistry.
