Three novel mixed-ligand lithium aggregates, [(mu3-EDBP)Li-2](2)[(mu (3)-Bu-n)Li(0.5Et(2)O)](2) (1), E(mu (3)-EDBP)Li-2](2)[(mu (3)-OBn)Li](2) (2), and [(mu (3)-EDBP)Li-2](2)[(mu3-OCH2CH2OCH2CH3)Li](2) (3), have been synthesized and structurally characterized. The reaction of 2,2 ' -ethylidene-bis(4,6-di-tert-butylphenol) (EDBP-H-2) with 3.6 molar equiv of (BuLi)-Bu-n gives 1 in high yield. 1 further reacts with benzyl alcohol and 2-ethoxyethanol respectively to yield the corresponding products 2 and 3. Experimental results show that 2 and 3 efficiently initiate the ring-opening polymerization of L-lactide in a controlled fashion, yielding polymers with very narrow polydispersity indexes in a wide range of monomer-to-initiator ratios.
