  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.

  Highly efficient cis-polymerization of butadiene was achieved by using new bis(indenyl) silylamide rare earth complexes with the cooperation of both a borate salt and i-Bu3Al; treatment of these complexes with organoboron compounds unexpectedly yielded new cationic mono(indenyl) amido species relevant to polymerization.

  Abstract A series of substituted-cyclopentadienyl molybdenum allyl derivatives has been prepared by reacting (η 3 -C 3 H 5 ) 3 MoCl with substituted-cyclopentadienyl and -indenyl alkali metal salts. In general, the isolated products are of the type Cp′Mo(η 3 -C 3 H 5 ) 2 and in three cases this has been confirmed by crystal structure determinations. Spectroscopic evidence suggests that at low temperatures

  摘要通过使（η3 -C 3 H 5）3 MoCl与取代的环戊二烯基和-茚基碱金属盐反应，制备了一系列的取代环戊二烯基钼烯丙基衍生物。通常，分离出的产物为Cp'Mo（η3 -C 3 H 5）2类型，这在三种情况下已通过晶体结构测定得到证实。光谱证据表明，在低温下还形成了具有Cp'Mo（η3 -C 3 H 5）2（η1 -C 3 H 5）组成的化合物。与芴基钾的反应是反常的：NMR光谱和晶体结构确定表明，产物（η3-芴基）Mo（η3 -C 3 H 5）3包含四个与金属不对称键合的η3-烯丙基原子。
