2-bromo-1-vinylnaphthalene. The reactivity of this new BN-phenanthrene, and of several substituted derivatives, has been tested against bromine and organolithium compounds. Bromination proceeded with complete regioselectivity, affording bromo-substituted compounds suitable for further functionalization via cross-coupling reactions. This new family of BN-phenanthrenes exhibits a substantial increase
以前未知的1,2-二氢-1-氮杂-2-硼菲是从2-溴-1-乙烯基萘仅三步合成的。已测试了这种新的BN菲和几种取代衍生物对溴和有机锂化合物的反应性。溴化以完全的区域选择性进行,得到适合于通过交叉偶联反应进一步官能化的溴取代的化合物。相对于菲,这个新的BN菲族显示出量子产率的显着提高(最高达ϕ F = 0.93)。
