【摘要】 苯和草酰氯单乙酯在三氯化铝作用下发生傅克反应,在低温(0℃)条件下生成苯乙酮酸乙酯,而在高温(70℃)条件下首次得到了9,10-二甲基蒽,其结构经1H NMR,13C NMR和单晶X-衍射仪表征。更多还原

【Abstract】 Benzene and ethyl chloroglyoxylate underwent Friedel-Crafts reaction in the presence of AlCl3 to give nomal product ethyl 2-oxo-2-phenylacetate at low temperature(0 ℃).However,when the reaction was performed at high temperature(70 ℃),an unusual product 9,10-dimethylanthracene was obtained as the main product for the first time.The structure was confirmed by 1H NMR,13C NMR and single-crystal X-ray diffraction.更多还原
