While alkali metal zincates have shown promising utility in organic synthesis, frequently these compounds are prepared in situ, and their identities remain blurred. Herein, the synthesis of a new family of sodium zincates featuring the chelating silyl(bis)amido ligand {Ph2Si(NAr*)2}2– (Ar* = 2,6-diisopropylphenyl) is presented.

By exploring the reactivity of sodium butyl-magnesiate (1) supported by the bulky chelating silyl(bisamido) ligand {Ph Si(NAr*) } (Ar* = 2,6-iPr -C H ) towards Quinoxaline (Qx), the ability of this bimetallic system to effectively promote SET processes has been disclosed. Thus 1 executes the single-electron reduction of Qx affording complex (2) whose structure in the solid state contains two quinaxolyl radical anions Qx˙ stabilised within a dimeric magnesiate framework.
