chemistry. We herein report the synthesis of formerly unknown 3,6-dibromo-2,7-dichlorotetrahaphthyridine and its employment in by Palladium catalysed Suzuki-Miyaura reaction. Synthesized 2,3,6,7-tetraarylnaphthtyridines have been obtained in generally good to excellent yields. The impact of donor- and acceptor substituents as well as the influence of acid on the optical properties have been studied by steady-state

化学。我们在此报告了以前未知的 3,6-dibromo-2,7-dichlorotetrahaphthyridine 的合成及其在
钯催化的 Suzuki-Miyaura 反应中的应用。合成的 2,3,6,7-四芳基
萘啶已经以一般良好到极好的产率获得。通过稳态紫外/可见光和荧光光谱研究了供体和受体取代基的影响以及酸对光学性质的影响,并通过循环伏安法和 DFT 计算进一步分析。
