Procedure

To a glass reaction container equipped with a cooling apparatus, 2.5 g of nickel bromide•ethylene glycol dimethyl ether, 2.56 g of 5,5′-bis(trimethylsilyl)-2,2′-bipyridine and 14 mL of ethanol were added at room temperature under a nitrogen atmosphere. The obtained mixture was reacted at 65° C. for 2 hours to obtain a crude product. The obtained crude product was recrystallized using hexane and ethanol to obtain 1.78 g of 5,5′-bis(trimethylsilyl)-2,2′-bipyridine nickel dibromide.
