termed H4-ED-DCP4 (2)} was elucidated. The reaction of 1 or 1a with the M(OR)4 precursor led to the isolation of the structural similar species M(ED-L4) where L = DBP, M = Ti (3), Zr (4), Hf (5); L = DAP, M = Zr (4a), Hf (5a). In contrast, the reaction of 2 with the M(OR)4 precursors yielded Ti(ED-DCP4) (6), (py)2Zr(ED-DCP4) (7), and (HOBut)Hf(ED-DCP4) (8) where py = pyridine and HOBut = HOC(CH3)3. For
