Novel Fulvalene Derivatives of Zirconium: A Facile Entry into Organozirconium(<scp>III</scp>) Chemistry

Abstract

A universally modifiable new starting substance, the fulvalene ZrIII complex 1, is formed upon reaction of Cp2ZrCl2 and sodium amalgam. 1 is highly reactive, but nevertheless it can be isolated. The fulvalene ligand ensures that the secondary products are dinuclear, e.g. [(CpZrCl)2(C5H4−C5H4)O], the oxidation product of 1.
