Conclusions
-
1.
The reaction of bis(cyclopentadienyl)zirconium dichloride or the dibromide with the salts CF3CO2Ag, CH3CO2Na, NaBr, and LiBr leads to the mixed bis(cyclopentadienyl) compounds of Zr with various ligands in the molecule.
-
2.
The reaction of Cp2ZrCl2 with excess CH3COOH in the presence of triethylamine at ∼20° gave CpZr-(OCOCH3)3.
