  Zirconium and hafnium complexes bearing new 1,2-ethanediyl- or 1,3-propanediyl-linked bis(β-diketiminate) ligands, [CnH2n-(BDIAr)2}MCl2] (Ar = 2,6-Me2-C6H3, 2,6-Cl2-C6H3, 2,6-iPr2-C6H3; M = Zr, n = 2 (4a–c), n = 3 (5a–c); M = Hf, n = 2 (6b)), were synthesized via the reaction of MCl4·2THF and one equivalent of dilithium salt of the corresponding ligand. Distorted trigonal prismatic and octahedral coordination geometries as well as C1-symmetric structures are found for zirconium complexes 4c and 5c in the solid state. Variable temperature 1H NMR spectra indicated the fluxional nature of 4a and 5a in solution. Upon activation with methylaluminoxane (MAO), all these complexes except hafnium complex 6b displayed moderate catalytic activities for ethylene polymerization. 1,2-Ethanediyl-linked complexes 4a and 4b are generally more active than their 1,3-propanediyl-linked analogues. The substituents at the ortho-positions of the phenyl rings have different effect on the catalytic activities of 1,2-ethanediyl-linked series or 1,3-propanediyl-linked series. It is noteworthy that even at a low Al/Zr molar ratio of 500, the catalytic activities of these zirconium complexes could be retained. Polyethylenes with broad molecular weight distributions (MWD = 15.3–20.3) were produced, which might result from the fluxional character of the zirconium complexes. The linear structure of obtained polyethylenes was further determined by 13C NMR spectroscopy and DSC analysis.

  Mesityl substituted beta-diketiminato lanthanum and yttrium complexes [(BDI)LnN(SiRMe2)}(2)] (BDI = ArNC(Me)CHC(Me)-NAr, Ar = 2,4,6-Me3C6H2, Ln = La, R = Me (1), H (2a); Ln = Y, R = H (2b)) can be prepared via facile amine elimination starting from [La(N(SiMe3)(2)}(3)] and [LnN(SiHMe2)(2)}(3)(THF)(2)] (Ln = Y, La), respectively. The X-ray crystal structure analysis of 1 revealed a distorted tetrahedral geometry around lanthanum with a eta(2)-bound beta-diketiminato ligand. A series of novel ethylene- and cyclohexyl-linked bis(beta-diketiminato) ligands [C2H4(BDAr)(2)]H-2 and [Cy(BDIAr)(2)]H-2 [Ar = Mes (=2,4,6-Me3C6H2), DEP (=2,6-Et2C6H3), DIPP (=2,6-i-Pr2C6H3)] were synthesized in a two step condensation procedure. The corresponding bis(beta-diketiminato) yttrium and lanthanum complexes were obtained via amine elimination. The X-ray crystal structure analysis of the ethylene-bridged bis(beta-diketiminato) complex [CyH4(BDIMes)(2)}YN(SiMe3)(2)] (3b) and cyclohexyl-bridged complexes [Cy(BDIMes)(2)}LaN(SiMe2)(2)] (7) and [Cy(BDIDEP)(2)} LaN(SiMe3)(2)] (8) revealed a distorted square pyramidal coordination geometry around the rare earth metal, in which the amido ligand occupies the apical position and the two linked beta-diketiminato moieties form the basis. The geometry of the bis(beta-diketiminato) ligands depends significantly on the linker unit. While complexes with an ethylene-linked ligand adopt a cisoid arrangement of the two aromatic substituents, complexes with cyclohexyl linker adopt a transoid arrangement. Either one (3b) or both (7, 8) of the beta-diketiminato moieties are tilted out of the eta(2) coordination mode, resulting in close Ln(...)C contacts. The beta-diketiminato and linked bis(beta-diketiminato) complexes were moderately active in the copolymerization of cyclohexene oxide with CO2. A maximum of 92% carbonate linkages were obtained using the ethylene-bridged bis(beta-diketiminato) complex [C2H4(BDIMes)(2)}LaN(SiHMe2)(2)] (4). (c) 2005 Elsevier B.V. All rights reserved.
