摘要：

A method utilizing Rieke(R) zinc reagents is described for the synthesis of 5-(3-thienyl)pentanenitrile from which 5-(3-thienyl)-N-acetylpentanamide and 5-(3-thienyl)-N-(4-trifluoromethyl)benzoylpentaneamine have been prepared. A study of the effect of different catalysts on the product composition and extent of conversion has been carried out. The method should be widely applicable to the synthesis of 3-alkylthiophenes bearing functional groups on the side chain which have been rather difficult to prepare previously. The characterization and oxidative polymerization/oligomerization of the new compounds is described. (C) 2003 Elsevier Science B.V. All rights reserved.
