Ouyang, Hao published the artcileSynthesis and Characterization of Dinuclear Salan Rare-Earth Metal Complexes and Their Application in the Homo- and Copolymerization of Cyclic Esters, Name: N1,N2-Dibenzylethane-1,2-diamine, the publication is Inorganic Chemistry (2018), 57(15), 9028-9038, database is CAplus and MEDLINE.
Four rare-earth-metal aryloxo complexes stabilized by a tetradentate Salan ligand were prepared, and their catalytic properties for the (co)polymerization of lactides and ¦Å-caprolactone were elucidated. The proton-exchange reactions of (C5H5)3Ln(THF) with the Salan ligand N,N’-(CH2Ph)2-N,N’-[CH2(2-OH-C6H2-Me2-3,5)]2 (LH2) in a 1:1 molar ratio, and subsequently with 1 equiv of p-methylphenol, gave the rare-earth-metal aryloxides [LLn(OC6H4-4-CH3)(THF)n]2 [n = 0 and Ln = Y (1), Sm (2), and Nd (3); n = 1 and Ln = La (4)] in good isolated yields. These complexes were fully characterized by elemental anal., IR, and NMR spectroscopy (for complexes 1 and 4). Solid-state structures of complexes 1-4 were confirmed by single-crystal X-ray diffraction anal. Complexes 1-4 have dinuclear solid-state structures, with a Ln2O2 core bridging the Salan ligands. The coordination geometry around each of the metals is a slightly distorted octahedron in complexes 1-3, whereas it is a capped trigonal prism in complex 4. It was found that complexes 1-4 can initiate efficiently the homopolymerization of
