Anthrone 1 and picolyl chloride hydrochloride 2 reacted in refluxing toluene for 2 h to give 10,10-bispyridinylmethyl-9(10H)-anthrones (3) in 63%～68% yields. Reduction of 3 with NaBH4 at 80 ℃ afforded 10,10-bispyridinylmethyl-9,10-dihydroanthracen-9-ols (4) in 87%～90% yields. The disproportionation reaction of 4 with acid as catalyst gave the reduced product, 10,10-bispyridinylmethyl-9,10-dihy- droan-thracenes (5) and the oxidized product, anthrones 3. The disproportionation reaction was influenced by catalyst, solvent and reaction temperature. When 4 was catalyzed by BF3 in refluxing toluene, the highest yield of 5 was up to 74%. The structures of all new compounds were confirmed by 1H NMR, 13C NMR, MS techniques and elemental analysis.

Key words: 10,10-bispyridinylmethyl-9,10-dihydroanthracenes, 10,10-bispyridinylmethyl-9(10H)-anth- rones, 10,10-bispyridinylmethyl-9,10-dihydroanthracene-9-ols, disproportionation, BF3
