Reaction Steps

Manganese (IV) oxide (2.8 g, purity 90%, 29.5 mmol) was added to a dichloromethane (20 ml) solution of 1,1-bis(6-phenylpyridine-2-yl)methanol (1.0 g, 3.0 mmol) obtained by Example 19, and this reaction mixture was stirred for 1 hour at room temperature. The obtained reaction mixture was filtered by silica gel, the solvent of the filtrate was distilled off, and the residue was purified by recrystallization, thereby obtaining 920 mg of 2,2′-carbonylbis(6-phenylpyridine) as white powder. Yield: 92.7%.
