catalysts such as [RhCl(PPh3)3] or [[RhCl(COD)]2] with PiPr2(OAr) or P(NMe2)3 co-catalysts allows the ortho-selective intermolecular arylation of phenols. The reaction proceeds via orthometalation of P-OAr groups and then transesterification liberates the product phenol. When 2-substituted phenols are used as substrates, [RhCl(PPh3)3]/iPr2(OAr) mixtures are typically the catalysts of choice, whereas for substrates
铑催化剂,例如[RhCl(PPh3)3]或[[RhCl(COD)] 2]与PiPr2(OAr)或P(NMe2)3助催化剂的结合,可使酚进行邻位选择性分子间芳基化。该反应通过P-OAr基团的正金属化而进行,然后酯交换反应释放产物苯酚。当使用2-取代的苯酚作为底物时,[RhCl(PPh3)3] / iPr2(OAr)混合物通常是选择的催化剂,而对于没有2-取代的[[RhCl(COD)] 2] / P(NMe2 )3混合物往往会产生更好的结果。
