Synthesis, mechanism and ethylene polymerization catalysis of Ge(iv), Sn(ii) and Zr(iv) complexes derived from substituted β-diketiminates

Unusual X-ray characterized crystalline Sn(ii), Ge(iv) and Zr(iv) complexes have been prepared via a salt metathesis and elimination reaction.

Inserted products of lithium silylquinolylamide dimers [{8-(2-R-C9H5N)N(Me3Si)}Li·OEt2]2 (R = H or Me) with dimethylcyanamide and their reactive derivatives with metal halides

Li, Ti, Fe and Co complexes bearing 8-quinolyl-linked guanidinate ligands have been synthesized and characterized. The structures of all complexes show various coordinative modes with the same multi-dentate ligands.
