Fig. 4 Cyclic voltammetric behavior of [CuBrL]2[Cu2Br4] (L = 2, 6-bis[l-(2,6-diisopropylphenylinnino)ethyl] pyridine as a function of scan rate (a) v = 0.1, (b) V = 0.2, (c) i> = 0.5, and (d) v = 1.0 V s. Peaks A and A are attributed to the Cu 7 BrL moiety while peaks B and B are assigned to the Cu"/ L redox couple in which the Cu—Br bond is dissociated. Reproduced with permission from Ref 120.

Kipke et al. (3) prepared 2,6-bis[l-(2,4-dichloro-6-methylphenylimino)ethyl]-pyridine iron(II) dichloride and bis(n-butylcyclopentadienyl)hafnium dichloride which when blended with an MAO were effective in preparing polyethylene for injection moldings.

A round-bottom flask was charged with a mixture of 2,6-dimethylphenyl trifluoromethanesulfonate (127.1 mg, 0.5 mmol), anhydrous lithium chloride (4 mmol), copper(I) bromide (0.2 mmol), and dichlorobis(triphenylphosphine)-palladium(II) (10-20 mol %) suspended in DMF (2.5 cm ). 2-Methoxyphenyl-tributyltin (1-1.5 mmol) was added to the mixture in two portions, i.e., at the beginning of the reaction and at half completion. A crystal of 2,6-bis(l,l-dime-thylethyl)-4-methylphenol (BHT) was added as an inhibitor of radical processes, and the mixture was then heated to reflux, under argon, during 8 - 24 h. Water and Et20 (25 cm ) was added, and the organic phase was washed subsequently with hydrochloric acid solution (1.5 mol dm , 6 x 20 cm ), a saturated solution of potassium fluoride (5 x 20 cm ), and finally dried over anhydrous sodium sulfate. Evaporation to dryness furnished a residue and that was suspended in ethyl acetate and the insoluble material was filtered off. The filtrate was...

Ray et al. [24] treated Cloisite 20A (montmorillonite modified with dimethyl-ditallow-containing approximately 65% Cig, 30% Cis, and 5% Ci4-ammonium cation chains) with a MAO solution, after vacuo-drying at 100 °C. The resulting MAO-treated clay was subsequently used for ethylene polymerizahon in the presence of a late transition metal catalyst (2,6-bis[l-(2,6-diisopropylphenylimino)ethyl] pyridine iron(ll) dichloride) and additional MAO in a glass reactor. They compared the result with homogeneous polymerization with the same catalyst in the presence of Cloisite 20A and observed that the supported catalyst was more efficiently exfoliated than when only a mixture of catalyst and clay was used. This comparison led them to conclude that at least some of the active centers resided within the clay galleries. Inductively coupled plasma (ICP) measurements showed that all MAO and catalyst remained in the solid catalyst after drying.
