Cp/amido titanium complex (η5-C5H4−CHMe−NPh-κN)Zr(NMe2)2 (2b). Analogous treatment of Cl2Zr(NEt2)2(THF)2 (7b) with 6a or 6b furnished the related (CpCN)Zr complexes (C5H4−CHR−NPh)Zr(NEt2)2 (2c, R = CH3; 2d, R = p-tolyl) each in ≥70% yield. The complexes 2a and 2b were both characterized by X-ray crystal structure analyses. The observation that both exhibit Cp(centroid)−M−N angles that are by ca. 10° smaller
