Copper(II) azido complex [CuL(μ-1,3-N3)] n (1) of a NNO donor tridentate Schiff base (HL = 2-[1-(methylamino-ethylimino)-methyl]-phenol containing single end-to-end μ-1,3-azido bridged 1D infinite chain has been synthesized and characterized by elemental analysis, FT-IR spectroscopy. X-ray single crystal structure analysis reveals that in 1, the central copper(II) ion displays a distorted square pyramidal coordination geometry and are linked by single EE azide bridges forming chains running parallel to the crystallographic b axis. The magnetic interaction revealed that 1 is antiferromagnetic in nature (J = -19.5 (±0.2) cm-1). The catalytic activity of the complex is investigated in a series of solvents for the oxidation of olefins using tert-butyl-hydroperoxide as oxidant. The results showed highest selectivity for 1 in acetonitrile medium.

All lined up: C1-symmetric octahedral titanium complexes (see structure, Ti dark gray, N blue, O red, I purple) whose labile positions reside in different electronic environments were designed using the readily available salalen ligands. With methylalumoxane as co-catalyst, highly active catalysts were obtained, which yielded high-molecular-weight polypropylene with ultra-high isotacticities (see 13C NMR spectrum) and melting transitions.

Page/Page column 52-53, (2012/01/06)
Use of homogeneous catalytic systems which include as a pre-catalyst a complex of a Group IV metal and a salalen ligand in the polymerization of alpha-olefins, is disclosed. The alpha-olefin polymers obtained are characterized by controlled levels of tacticity. Also disclosed are novel salalen ligands and novel complexes thereof with Group IV metals.
