The development of an Ir-catalyzed ortho-C-H borylation of aromatic aldimines derived from pentafluoroaniline is reported. This reaction proceeded at 120 °C to afford the corresponding borylated products in high yield with good regioselectivity using an Ir complex formed in situ from [Ir(OMe)(cod)]2/2(C6F5)3P in the presence of 2-norbornene.
报道了一种铱催化的源自五氟苯胺的芳香醛亚胺的邻位C-H硼化反应。该反应在120℃下进行，在2-降冰片烯存在下，使用由[Ir(OMe)(cod)]2/2(C6F5)3P原位形成的铱配合物，以高收率和良好的区域选择性得到相应的硼化产物。
