A substantial effect on the reactivity of a common complex base is observed by the addition of metal salts MXn (M = Mg, Zn, Cu, Zr); a template effect of the new aggregates is proposed. ... We have previously showed that the complex bases NaNH2– RONa (RONa was a sodium alkoxide or ketone enolate) are useful reagents in organic synthesis.1 The behaviour of such unimetal super bases2 stems from the formation of aggre- gates3 whose properties are governed ...
