摘要

Simple and mild Cu-mediated arylation of various amines by use of tetraarylantimony acetate (Ar 4 SbOAc) is described. The Ullmann-type condensation of Ar 4 SbOAc with aliphatic and electron rich aromatic amines proceeded efficiently in the presence of copper (II) acetate. The arylation can be carried out under aerobic conditions without care of exogenous oxygen. This simple procedure exceeds the conventional Ullmann ...
