Highly functionalized diaryl ethers were prepared by copper(II) acetate mediated O-arylation reaction of phenols using trivalent organobismuthanes. The reaction is performed under simple conditions and tolerates a wide diversity of functional groups on the phenol and on the organobismuth reagent. Substoichiometric amounts of catalyst can be used by performing the reaction under an oxygen atmosphere. The N-arylation of pyridones is also reported.
通过使用三价有机铋化合物，在醋酸铜（II）介导下使酚类进行O-芳基化反应，制备了高度官能化的二芳基醚。该反应在简单的条件下进行，并且对酚类和有机铋试剂上的多种官能团具有耐受性。通过在氧气气氛下进行反应，可以使用亚化学计量的催化剂。还报道了吡啶酮的N-芳基化反应。
