  Five-coordinate β-ketoiminate derivatives of the (N3-macrocycle)nickel(II) fragment (N3-macrocycle = 2,4,4-trimethyl-1,5,9-triazacyclododec-1-ene and its 9-methyl derivative)

  摘要：

  The hydroxo complexes [{Ni(N-3-macrocycle)(mu-OH)}(2)](ClO4)(2) (N-3-macrocycle = 2,4,4-trimethyl-1,5,9-triazacyclododec-1-ene (N-3-mc) and 2,4,4,9-tetramethyl-1,5,9-triazacyclododec-1-ene (9-Me-N-3-mc)) react with the appropriate beta-ketoimine to give five-coordinate nickel(II) complexes of the type [Ni(N-3-macrocycle) (C6H5COCHC(NR)CH3)](ClO4). The complexes have been studied by spectroscopic (IR, UV-vis, H-1 NMR and NOE) and thermal methods. An X-ray diffraction study carried out with the complex [Ni(9-Me-N-3-mc) {C6H5COCHC(NC6H5)CH3}](ClO4) has established that the Ni atom presents a square pyramidal coordination and is displaced 0.325(1) Angstrom out of the basal plane towards the apical N1 atom.

  New titanium complexes with two nonsymmetric bidentate beta-enaminoketonato (N,O) ligands (4a-e), [(Ph)NC(R-2)C(H)C(R-1)O](2)TiCl2, have been synthesized. X-ray crystal structure reveals that complex 4a has a C-2-symmetric conformation with a distorted octahedral geometry around the titanium center. With modified methylaluminoxane (MMAO) as a cocatalyst, complexes 4a-e are active catalysts for ethylene polymerization at room temperature, producing high molecular weight polyethylenes bearing linear structures. The 4a,b/MMAO catalyst systems exhibit the characteristics of a quasi-living polymerization of ethylene, producing polyethylenes with narrow molecular weight distributions. Moreover, the 4a-d/MMAO catalyst systems are also capable of promoting the quasi-living copolymerization of ethylene with norbornene at room temperature, yielding high molecular weight alternating copolymers with narrow molecular weight distributions. The quasi-living nature of the catalysts allows the synthesis of new A-B polyethylene-block-poly(ethylene-conorbornene) diblock copolymer.
