An efficient and practical synthesis of 2,7-bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)triphenylene 4 from two cheap commodity chemicals in five steps with a total yield of 48.6% was developed. This process had been successfully applied in the synthesis of electron transport material (ETM) BPyTP-2 in the gram scale with a total yield of 47.2%. This practical development of the key intermediate
由两种廉价的商品化学品以五个步骤高效,实用地合成2,7-双(4,4,5,5-四甲基-1,3,2-二氧杂硼杂环戊烷-2-基)三亚苯基4,总收率为48.6 % 发展了。该工艺已成功用于克级电子传输材料(ETM)BPyTP-2的合成,总收率为47.2%。关键中间体4的这一实际发展为它在合成材料领域中其他基于三亚苯基的ETM和主体材料的进一步应用打开了一扇门。
