Ligand-metal interaction in transition-metal complexes with tripodal polyaza ligands

Five complexes ([Cu(tpc)]²⁺ 1, [Cu(tpa)]²⁺ 2, [Co(tpa)]²⁺ 3, [Fe(tpa)]²⁺ 4 and [Mn(tpa)]²⁺ 5) (tpc=N, N’, N"-tris[(2-pyridyl)methyl]-1,4,7-triaza-cyclononane(L1) and tpa=tris[2-((2-pyridyl) methyl-imino)ethyl]amine(l2)) were synthesized and characterized. The crystal structures of 1, 3 and 4 were determined by X-ray crystallography. Electrochemical investigations over two cupric complexes reveal that 2 has a less negative redox potential than that of 1. Electronic spectra of 2, 3, 4 and 5 show that the distinction in metal ion results in a shift of the ligand-based π*→π transition. Foundation item: Supported by the Natural Science Foundation of Hubei province Biography: Yin Ye-gao (1950-), male, Associate professor, researching for the the synthsis and properties of tripodal polydentate ligands.     

Half-sandwich rhodium polychalcogenide complexes and a carbon insertion into Te-Te bond

Treatment of CptRh(PMe3)Cl2(1) (Cpt = 5(- tBu2C5H3) with [Et4N]2Se6 in DMF solution leads to the formation of cyclo-tetraselenido half-sandwich rhodium complexes CptRh(PMe3)(Se4) (2). The elimination of 2 with excess of nBu3P results in cyclo-diselenido rhodium complex CptRh(PMe3)(Se2) (3). 1 reacts with [nBu4N]2Te5 in DMF solution to yield cyclo-ditellurido rhodium complex CptRh (PMe3)(Te2) (4) in which carbon atom from CH2Cl2 can be inserted into Te-Te bond to form CptRh(PMe3)(TeCH2Te) (5). The new complexes 2-5 have been characterized by their IR, EI-MS, and 1H, 13C, 31P, 103Rh NMR spectra as well as elemental analysis.

Well-defined bis（phenolate） lanthanide methoxides as efficient initiators for the polymerization of cyclic carbonate and lactide

Lanthanide methoxides supported by carbon-bridged bis(phenolate) ligands 2,2′-methylene-bis(6-tert- butyl-4-methylphenoxo) (MBMP2-) [(MBMP)Ln( μ-OMe)(THF)2]2 (Ln = Nd (1), Yb (2)) were synthesized in high yields by the protolysis reaction using (C5H5)3Ln(THF) as starting materials, and complex 1 was structurally characterized. The coordination geometry around the center metal can be best described as a distorted octahedron. Complexes 1 and 2 were shown to be efficient initiators for the ring-opening polymerization of 2,2-dimethyltrimethylene carbonate (DTC) and L-lactide. The mechanism of DTC polymerization was explored by the end group analysis of the oligomer.
