Electron transference in hemolytic aromatic substitution reactions

Abstract

The selectivity of methyl radicals in the homolytic substitution reaction on naphthalene was studied as a function of solvent. The selectivity decreases as the solvent dielectric increases. A possible explanation of these effects based upon a charge-transfer contribution to the transition state leading to o-complex formation is offered.

“…Solvent effects have been observed in connection with selectivity in aromatic [29][30][31][32][33] and aliphatic [34][35][36] substitution reactions. Such effects have also been reported in hot-atom chemistry but little is still known, particularly of the influence of the solvent in connection with its type and amount present in a reaction [3,[24][25][26][27][28].…”
