A series of BN-incorporated borafluorenate heterocycles, bis(borafluorene-phosphinimine)s (-), have been formed via molecular Staudinger-type reactions. The reactions were promoted by light or heat using monodentate phosphine-stabilized 9-azido-9-borafluorenes (RP-BF-N; -) and involve the release of dinitrogen (N), migration of phosphine from boron to nitrogen, and oxidation of the phosphorus center (P to P). Density functional theory (DFT) calculations provide mechanistic insight into the formation of these compounds. Compounds - are blue emissive in the solution and solid states with absolute quantum yields (Φ) ranging from 12 to 68%.
通过分子施陶丁格型反应形成了一系列含硼氮的硼芴杂环化合物，双（硼芴-膦亚胺）（-）。这些反应在光或热的作用下，使用单齿膦稳定的9-叠氮基-9-硼芴（RP-BF-N；-）进行，涉及氮气（N₂）的释放、膦从硼迁移到氮以及磷中心的氧化（P(III)到P(V)）。密度泛函理论（DFT）计算为这些化合物的形成提供了机理见解。化合物-在溶液和固态中均发出蓝色荧光，绝对量子产率（Φ）范围为12%至68%。
