Aryliminodimagnesium Reagents. VII. The Moderate Electron-donating Ability Estimated by Oxidation Peak Potentials

Oxidation peak potentials of p-RC6H4N(MgBr)2 and p-RC6H4MgBr (R=CH3O, CH3, F) were determined by cyclic voltammetry with a platinum disk electrode in tetrahydrofuran. The potentials obtained proved to be a semiquantitative measure of electron-donating abilities of organomagnesium reagents.
