has been synthesized in only three steps (76% overall yield) from easily accessible 1-bromo-2-vinylnaphthalene, along with several substituted derivatives. The reactivity of these previously unknown BN-aromatic compounds toward organolithium compounds and bromine has been studied. This latter reaction affords bromo-substituted compounds that are suitable for further functionalization via Suzuki and Sonogashira
3,4-Dihydro-4-aza-3-boraphenanthrene,显示了迄今为止报道的所有未取代的BN-菲的最高荧光量子产率(ϕ F = 0.61),仅通过三步合成(总产率的76%)容易获得的1-溴-2-乙烯基萘,以及几种取代的衍生物。已经研究了这些先前未知的BN-芳族化合物对有机锂化合物和溴的反应性。后一反应提供了溴取代的化合物,其适合于通过Suzuki和Sonogashira偶联进一步官能化,具有完全的区域选择性。使用计算方法研究了所选化合物的光学性质和激发态失活机理。
