    Zirconocene dipicolinate and related dicarboxylate complexes: Coordination geometries and reactivities
    摘要:
    Monomeric zirconocene dipicolinate complexes, which have a formal 18-electron configuration, are stable towards water and relatively inert against aqueous HCl. Methylmagnesium chloride attacks these complexes at the dipicolinate carboxyl groups and subsequent reaction with aqueous HCl gives 2,6-diacetyl pyridine and the zirconocene dichloride. Other dicarboxylates, such as 3,4-dimethoxyfurane-2,5-dicarboxylate or isophthalate, form binuclear zirconocene complexes, in which one bidentate and one monodentate carboxylate ligand generate a formal 18-electron configuration. These complexes react with methylmagnesium chloride to give the respective zirconocene dimethyl complexes, i.e. by normal replacement of C=O bonds by C-CH3 bonds.

Spectroscopic studies have led us to believe that 10a is characterized by an internal ether-chelate structure in solution that involves coordination of the 6-OCH2Ph oxygen atom. Treatment of 10a with trimethylphosphane gives the open, non-chelated complex 11a, in which the phosphane coordinates to the metal center.
