Synthesis of a series of bis(alkylamidinate) group 4 compounds of the general formula M(CyNC(CH3)NCy)2Cl2 (M = Ti (1), Zr (2), Hf (3); Cy = cyclohexyl), Zr(CyNC(CMe3)NCy)2-Cl2 (4), and Zr(CyNC(CH3)NCy)2(CH3)2 (5) are reported. In the presence of methylaluminoxane (MAO) as a cocatalyst, compounds 1-5 are active ethylene polymerization catalysts.
