... being the major products. The ethylene oligomerization activity was found to be affected by the substituents on the ligand framework. Incorporation of sterically bulky and electron donating groups on the carbon atom neighboring the coordinating nitrogen of the oxaline ring led to a decrease in catalytic...

... abstraction by peroxy radicals is mainly determined by the strength of the bond which is broken and the transition state for this reaction must largely resemble the products. Polar contributions to the transition state are also important since electron-attracting substituents on the hydrocarbon decrease...
