摘要：

We have found that N,N-dimethylethanolamine (deanol) is a useful solvent and ligand for copper catalyzed amination of a variety of unactivated and activated 2- or 3-halothiophenes. Primary amines, acyclic secondary amines, cyclic secondary amines and acyclic secondary amines with 2-hydroxyethyl functionality react with halothiophenes in moderate to excellent yields. The mildly basic conditions utilized are compatible with many functional groups. The animation of halobithiophenes has also been examined. The aminothiophenes produced by this method are important intermediates in a variety of electronic and optoelectronic materials. (C) 2004 Elsevier Ltd. All rights reserved.
