olefination of tertiary anilines without a directing group was developed. This reaction tolerated various substituted arenes and olefin coupling partners, affording ortho-olefination products in moderate to good yields. Preliminary mechanistic studies showed that N-Ac-d-Ala, Ag2CO3, and BQ were the key factors for tuning the regioselectivity from para to ortho. Density functional theory was used to achieve
开发了一种不带导向基团的叔苯胺的高邻位选择性C Ar -H 烯化反应。该反应耐受各种取代的芳烃和烯烃偶联配对物,以中等至良好的产率提供邻烯化产物。初步机理研究表明, N -Ac- d -Ala、Ag 2 CO 3和BQ是将区域选择性从对位调整为邻位的关键因素。密度泛函理论用于实现对邻位选择性的理论理解。
