Изобретение относится к органической химии, а именно к способу получения производных триптицена, в частности к получению трис-ацетилтриптицена с заместителями в бета -положениях трех различных колец триптиценового фрагмента. Целью изобретения является разработка удобного и простого способа получения трис-ацетилтриптицена. Триптицен последовательно ацетилируют сначала хлористым ацетилом в нитрометане в присутствии бромида алюминия, а затем - хлористым ацетилом в дихлорэтане в присутствии хлорида алюминия, нитрометана и хлористого водорода при мольном соотношении триптицен: нитрометан: газообразный хлористый водород 1 : (2 - 5) : (0,025 - 0,18) с последующим выделением продукта известным методом. Предлагаемый способ позволяет повысить выход с 21 до 52% и существенно упростить способ за счет сокращения числа стадий с четырех до двух.The invention relates to organic chemistry, in particular to a method for producing trypticene derivatives, in particular to the preparation of tris-acetyltryptene with substituents in beta-positions of three different rings of the tryptycene fragment. The aim of the invention is to develop a convenient and simple way to obtain Tris-acetyltryptocene. Trypticen is successively acetylated first with acetyl chloride in nitromethane in the presence of aluminum bromide, and then with acetyl chloride in dichloroethane in the presence of aluminum chloride, nitromethane and hydrogen chloride at a molar ratio of triptycene: nitromethane: gaseous hydrogen chloride 1: (2-5): (0.025 - 0.18) followed by isolation of the product by a known method. The proposed method allows to increase the yield from 21 to 52% and significantly simplify the method by reducing the number of stages from four to two.
