9,10-菲醌选择性溴化反应研究
Selective Bromination of 9,10 Phenanthrenequinone
摘要
Abstract
A series of 9,10-phenanthrenequinone bromides were selectively synthesized by varying reaction conditions such as the molar ratio of reactants , the type of solvent and the reaction temperature .2-bromine-9,10-phenanthrenequinone was prepared by mixing 9,10-phednanthrenequinone with N-bromobutanimide in a molar ratio of 1.0∶1.4 at 0 ℃ for 3 h with concentrated sulfuric acid as solvent , and a 60%yield was obtained.Under similar condition, 76%yield of 2,7-dibromo-9,10-phenanthrenequinone was obtained with a molar ratio of 9, 10-phenanthrenequinone to N-bromobutanimide of 1.0∶2.3 at room temperature.85% yield of 3-bromine-9, 10-phenanthrenequinone was prepared by mixing 9, 10-phednanthrenequinone and bromine in a molar ratio of 1.0∶1.4 at 106 ℃for 3 h with acetic acid as solvent , and benzoyl peroxide as initiating agent .90%yield of 3,6-dibromo-9,10-phenanthrenequinone was obtained with the molar ratio of 9, 10-phenanthrenequinone to bromine of 1.0∶3.4 at the same condition. The selective bromination of 9, 10-phenanthrenequinone was discussed and it was found that the amount of brominating reagent was the major factor determining the production of monobromide or dibromide .关键词
