: Zr(IV) “metalloazines” have been prepared from Zr(IV) salts and hydrazone derivatives (or from Zr-(II) phosphine complexes and diazoalkanes). They are dimeric; X-ray analysis reveals an unsymmetrically bridged dizirconium center, and NMR analysis shows that the complexes are fluxional. They demonstrate susceptibility to electrophilic attack at carbon and thus represent an “umpolung” of the carbonyl group from which they were derived.
