The reactions of 9-borafluorenes with organic azides result in either the insertion of the α-nitrogen and elimination of N2 or the insertion of the γ-nitrogen to generate the corresponding phenanthrene analogues with boron and nitrogen in the 9- and 10-positions, respectively.
9-硼杂芴与有机叠氮化物的反应,要么发生α-氮插入和 N2 消除,要么发生γ-氮插入,分别在 9 位和 10 位生成相应的带有硼和氮的菲衍生物。
