While most activity in heterobimetallics concerns transition metals, co-operative effects between two distinct metals are also attracting worldwide attention within main group chemistry. Current interest focuses on synthetic applications of bimetallic reagents, where an alkali metal activates another main group metal such as magnesium, aluminium, or zinc.This presentation will outline our recent contributions to this area. We demonstrate how such cooperative effects between these distinct metals can produce surprising reactions outside the scope of single metal reagents. This will include examples of structurally defined metallation reactions of aromatic substrates that exhibit special regioselectivities or polydeprotonations.Light will also be shed on the �black box� mystery of this chemistry. Using DOSY NMR studies we investigate whether these reagents are bona fide mixed metal ATE species.Furthermore we introduce new types of zincates, structurally distinct to existing literature zincates, that are effective alkylating reagents. Catalytic implications of these reactions are discussed.
