Aryliminodimagnesium (ArN (MgBr) <SUB>2</SUB>, IDMg) reacts with various kinds of substrates in the modes of condensation, addition, replacement, and coupling. Many reactions of this N-Mg and also C-Mg (Grignard) reagents were classified in terms of “efficiency of single electron transfer (SET)” using the difference between oxidation and reduction potentials of reactants (Δ<I>E</I>=<I>E</I><SUB>ox</SUB>-<I>E</I><SUB>red</SUB>). The minor factors disclosed from detailed distribution of normal and abnormal products are those arising from “aggregation of excess reagent molecules” and from “σ-complexation of reactants”. The former factor participates in common to the N-Mg and C-Mg reactions of medium Δ<I>E</I>, whereas the latter factor participates in common to three reactions of large Δ<I>E</I> using N-Mg which is weakly electron-donating. Usefulness of the Δ<I>E</I>-approach for structure-reactivity study and also synthetic use of various magnesium reagents were discussed.
