Zirconocene dipicolinate and related dicarboxylate complexes : coordination geometries and reactivities deposit-license Diebold, Josef Journal of Organometallic Chemistry ; 456 (1993), 2. - S. 195-204 Troll, Carsten Brintzinger, Hans-Herbert Troll, Carsten 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-CH<sub>3</sub> bonds.
