  Cationic Nickel Complexes Containing Bulky Phosphine Ligands:  Catalyst Precursors for Styrene Polymerization

  摘要：

  The cationic complexes [Ni(eta(3)-CH2C(R)CH2)(P)(2)] [BPh4] (R = Me, H; (P)(2) = ((PMePr2)-Pr-i)(2), ((PPhPr2)-Pr-i)(2), 1,2-bis(diisopropylphosphino)ethane (dippe)) and [Ni(eta-2-MeInd)(P)(2)] [BPh4] (2-MeInd = 2-methylindenyl; (P)(2) = ((PMePr2)-Pr-i)(2), ((PPhPr2)-Pr-i)(2), dippe) have been prepared and characterized. These materials are catalyst precursors for the nonliving polymerization of styrene to polystyrene without the need of a cocatalyst such as methylaluminoxane. The polymerization reactions are carried out in refluxing 1,2-dichloroethane, using a 1:1000 catalyst to styrene ratio, yielding essentially atactic polystyrenes with M-n in the range 14 500-155 000 Da and polydispersities between 1.89 and 9.70. The mass properties of the polymers and the overall yield depend much on the nature of the catalyst precursor.
