Palladium C–N bond formation catalysed by air-stable robust polydentate ferrocenylphosphines: a comparative study for the efficient and selective coupling of aniline derivatives to dichloroarene
The arylation of aniline derivatives with dichloroarenes under a low palladium content (below the currently used 5 to 10 mol%) was studied using nine different ferrocenylphosphine ligands, including the easily accessible 1,1′-bis(diphenylphosphino)ferrocene, DPPF. The electron-enriched air-stable tridentate ferrocenylpolyphosphine 1,2-bis(diphenylphosphino)-1′-(diisopropylphosphino)-4-tert-butylferrocene
使用九种不同的二茂铁基膦配体,包括容易获得的1,1'-双(二苯基膦基)二茂铁,DPPF,研究了钯含量低(低于目前使用的5-10 mol%)下苯胺衍生物与二氯芳烃的芳基化作用。电子富集的空气稳定的三齿ferrocenylpolyphosphine 1,2-双(二苯基膦基)-1' - (二异丙基)-4-叔-butylferrocene,L5,在2摩尔%与1摩尔%[的PdCl(采用组合η 3 - C 3 H 5)] 2允许有效和选择性的偶联,而目前这种要求苛刻的底物引发了氯芳烃均偶联和/或脱卤过程。探索了优化系统的范围和局限性,重点关注贫电子的氟苯胺(失活的亲核试剂)和富电子的甲基化和甲氧基化的二氯苯(失活的亲电试剂)。
