The title compound, C(10)H(8)BrN, was obtained by slow addition of sodium azide to 8-bromo-1-naphthoic acid, followed by addition of aqueous ammonia. The crude product was crystallized from petroleum ether to give pink crystals. Compared to other 1,8-disubstituted naphthalene compounds, this compound exhibits less strain between the 1 and 8 substituents. Additionally, the NH protons form both intra- and inter-molecular hydrogen bonds. The naphthalene units are arranged in a herring-bone stacking motif.
标题化合物C(10)H(8)BrN是通过将叠氮化钠缓慢加入到8-溴-1-萘甲酸中,然后加入氨水制得的。粗产物从石油醚中结晶得到粉红色晶体。与其他1,8-二取代萘化合物相比,该化合物在1和8取代基之间表现出较小的张力。此外,NH质子形成分子内和分子间氢键。萘单元以人字形堆积模式排列。
