聚（3-烷基噻吩）（PATs）具有良好的电子性能，然而，其区域规整合成才刚刚开始发展。作者描述了一种制备头-尾偶联（HT）PAT的新方法，其中利用甲基溴化镁来实现显示出出乎意料的高区域选择性的格氏复分解。该方法快速、经济且高产率地生产区域规则的HT-PAT，这使其具有良好的工业级生产潜力。
Poly(3-alkylthiophenes) (PATs) exhibit promising electronic properties; however, their regioregular syntheses are only beginning to be developed. The authors describe a new method for the preparation of head-to-tail coupled (HT) PATs, in which methylmagnesium bromide is utilized to effect a Grignard metathesis that displays unexpectedly high regioselectivity. The method produces regioregular HT-PATs quickly, economically and in high yields, which lends it excellent potential for industry-level production.
