in solution as well as in the solid state. DFT calculations suggest preferential interactions between 2-Pn and soft Lewis acids via the lighter pnictogen donor atom. Experimental studies demonstrate that even the weakest Lewis base in the series of 2-Pn, namely the dibismatriptycene 2-Bi, interacts with Lewis acidic [BiMe2(SbF6)] in solution. Analytical techniques include (VT-)NMR spectroscopy, DOSY
第一个系列的 9-bisma-10-pnictatriptycenes Bi(C 6 H 4 ) 3 Pn ( 2-Pn , Pn = P–Bi;见图)已通过合适的三(2-溴苯基)以两步法合成)pnictanes 1-Pn并在溶液和固态中进行表征。DFT 计算表明2-Pn和软路易斯酸之间通过较轻的磷元素供体原子优先相互作用。实验研究表明,即使是2-Pn系列中最弱的路易斯碱,即二双三苯乙烯2-Bi,也会与溶液中的路易斯酸 [BiMe 2 (SbF 6 )] 相互作用。分析技术包括 (VT-)NMR 光谱、DOSY NMR 光谱、高分辨率质谱、单晶 X 射线衍射分析和 DFT 计算。
