Özet
When 9, 10-dibromoanthracene was treated with bromine in CCl 4 without a catalyst, 1, 2, 3, 4, 9, 10-hexabromo-1, 2, 3, 4-tetrahydroanthracene (3) was obtained in 95% yield in the absence of other stereoisomers or rearomatization products. We investigated the base-induced elimination reaction of hexabromide 3 under various conditions. Pyridine-induced elimination of hexabromide 3 afforded 2, 9, 10-tribromoanthracene (12) in 75% yield, and tribromide 12 was transformed to trimethoxy compound 13 and trinitrile 14 by copper-assisted nucleophilic substitution reactions.
