A series of 2,6-dibenzhydryl-N-(2-phenyliminoacenaphthylenylidene)-4-methylbenzenamines (L1-L5) and the nickel(II) dibromide complexes thereof (C1-C5) were synthesized and fully characterized. The molecular structures of representative complexes were determined by single-crystal X-ray diffraction and revealed a distorted-pyramidal geometry at nickel. All nickel(II) procatalysts exhibited very high activity for the polymerization of ethylene, with activities as high as the range of 107 g of PE (mol of Ni)-1 h-1.
