novel, simple, and efficient approach for the synthesis of benzofulvene derivatives from o‐arylaniline substrates through C−H bond activation with two diarylacetylenes as an implicit benzofulvene unit. The reactivity of synthesized benzofulvenes toward oxidation was investigated, and they were shown to transform into phenanthridines, oxabenzofulvenes, and fluorescent polycyclics.
我们报告的Pd(II)的第一个例子中通过游离胺定向催化的高度步进和原子的经济benzofulvenation邻C-H键活化的Ó -arylanilines。本文提出了一种新颖,简单,有效的方法,可通过邻苯二甲酰苯胺底物通过CH键与两个二芳基乙炔作为隐式苯并富勒烯单元的活化作用来合成苯并富烯衍生物。研究了合成的苯并富勒烯对氧化的反应性,结果表明它们可转变成菲啶,氧杂苯并富烯和荧光多环化合物。
