Nickel complexes 3?6. A mixture of 1.00 g (3.2 mmol) of nitrile 1, 0.64 g (3.2 mmol) of nitrile 2, and 0.50 g (2.0 mmol) of nickel(II) acetate tetrahydrate was stirred during 1 h at 210 °C. After cooling the reaction mixture, it was dissolved in 50 mL of dichloromethane and filtered through a 5 cm layer of type II alumina. The solvent was distilled off, and the residue was purified by column chromatography on Kieselgel 60 silica gel (Merck). First, complexes 3 and 4 were isolated using dichloromethane as eluent, and then complexes 5 and 6 were isolated using a 95 : 5 (v/v) mixture of dichloromethane and ethanol as eluent.
