base-free dichloride complex (BAIP)ZrCl2 (5) can be prepared from 2 and excess ClSiMe3. The alkylation of 4 or 5 with 2 equiv of MeMgBr, 2 equiv of PhCH2MgCl, and 1 equiv of NaCp(DME) yields the alkyl derivatives (BAIP)ZrR2 (6a, R = Me; 6b, R = CH2Ph) and (BAIP)Zr(η5-C5H5)Cl (8), respectively. The reaction of 2 equiv of PhMe2CCH2MgCl with complex 4 yields the η2-pyridyl complex (BAIP)Zr(η2-N,C−NC5H4)(CH2CMe2Ph)
