摘要
The direct aryltion of activated thiophenes is achieved in moderate to good yields using a Heck-type reaction with a mixture of Pd(OAc)(2), n-Bu4NBr and a base as catalytic system. This new procedure is applied to different 2- and 3-substituted thiophenes, and parameters of thr reaction are studied. Based on these results, 3 new method for polymerization of various 2 -halogeno-3-alkylthiophenes is described using the same catalytic system and leading to expected regioregular functionalized oligomers with good yields.
