Acetyl aromatic compounds and diacetyl aromatic compounds were synthesized convenientlyby reactions of acetylation or oxidation based on aromatic compounds. All of the twelve acetyl aromatic compounds were confirmed by melting point (or boiling point) and ' H NMR. It was found that single acetylation for electron-rich aromatic compounds with multiple active positions (e. G. , N-ethylcar-bazole) was successfully realized by using relatively low activity of catalyst and acetylation reagent.%实验以芳环化合物为原料,通过酰基化、氧化反应等方法分别合成了单乙酰基芳环化合物:对乙基苯乙酮、对异丙基苯乙酮、4-乙酰基联苯、4-乙酰基二苯醚、3-乙酰基-N-乙基咔唑、N-乙酰基咔唑、2-乙酰基吡咯、2-乙酰基苯并咪唑；二乙酰基芳环化合物:对二乙酰苯、4,4′-对二乙酰联苯、4,4′-对二乙酰二苯醚、3,6-二乙酰基-N-乙基咔唑.通过熔点(沸点)、1H NMR等对化合物结构进行了确证.实验发现,具有多个活性位置的富电子芳环化合物(如N-乙基咔唑)应采用活性相对较低的催化剂/乙酰化试剂体系来实现单乙酰基化.
