para-substituted aryl groups, R. Values of the equilibrium constants, enthalpy, and entropy of the reactions are presented. The electronic effects of the aryl groups on this R migration reaction are found to be at least as critical as any previously reported factors influencing this process. Electron-donating substituents in meta- or para-positions promote the insertions, whereas electron-withdrawing groups inhibit

Radicalcations of dibenzylmercury and its p-X derivatives (X = Me, MeS, MeO, Cl) and of diphenylmercury and its p-X derivatives (X = Cl, Et, Me, MeO) have been generated by γ-radiolysis of dilute solutions of the parent compounds in CFCl3 matrices at 77 K. The EPR results for the dibenzylmercury series show all members to be σu-radical cations with singly occupied molecular orbitals approximating
