Efficient syntheses of the 3-, 9-, 10-, and 11-phenol isomers of dibenz[a,c]anthracene (DBa,cA) and 2,3-dihydroxy-DBa,cA are described. Bromination of DBa,cA with bromine in CH2Cl2 gave 10-bromo-DBa,cA and not 9-bromo-DBa,cA predicted theoretically. On the other hand, bromination of DBa,cA with NBS and FeCl3 furnished 9-bromo-DBa,cA.
描述了苯并[ a,c ]蒽(DB a,c A)和2,3-二羟基-DB a,c A的3-,9-,10-和11-苯酚异构体的有效合成。DB的溴化一个,Ç阿与溴在CH 2氯2,得到10-溴DB一个,Ç A和不9-溴DB一个,Ç甲理论预测。另一方面,用NBS和FeCl 3溴化DB a,c A可得到9-溴DB a,c A。
