3,6-trifluorophenylacetamide yielded a novel 2-hydroxyaryl substituted bisarylmaleimide (5h). We propose based on X-ray crystallographic evidence that this transformation occurs via formation of a previously undescribed tricyclic ring system (6h). The reactivity of the 2-halo analogues of the arylacetamide (3h) indicated that 2,6-disubstitution facilitated conversion compared to other substitution
2-甲氧基芳基乙二醛草酸酯与2,3,6-三氟苯基乙酰胺的反应产生了新的2-羟基芳基取代的双芳基马来酰亚胺(5h)。我们基于X射线晶体学证据提出,这种转变是通过形成先前未描述的三环系统(6h)发生的。芳基乙酰胺(3h)的2-卤代类似物的反应活性表明,与其他取代方式相比,2,6-二取代促进了转化。
