The discovery of catalyst‐transfer polymerization and its further developments have led to unprecedented control over the length and sequence of conjugated polymers. However, the methods themselves are technically challenging to perform due to the air‐ and moisture‐sensitivities of the monomers and catalysts. Herein, we report a catalyst‐transfer polymerization method that affords poly(3‐hexylthiophene) in high yields without using an inert atmosphere. The synthesis capitalizes on a rapid Negishi cross‐coupling using a moisture‐tolerant organozinc monomer mediated by an air‐stable Pd precatalyst. This simple method should make conjugated polymer synthesis more accessible to a broader range of researchers and may be generalizable to other monomer scaffolds.

通过催化剂转移聚合合成耐空气的聚（3-己基噻吩）

催化剂转移聚合的发现及其进一步的发展已导致对共轭聚合物的长度和顺序的空前控制。然而，由于单体和催化剂对空气和湿气的敏感性，这些方法本身在技术上具有挑战性。在本文中，我们报道了一种催化剂转移聚合方法，该方法可在不使用惰性气氛的情况下以高收率获得聚（3-己基噻吩）。合成利用了耐湿有机锌单体在耐气的Pd预催化剂介导下的快速Negishi交叉偶联。这种简单的方法应该使共轭聚合物的合成更易于广泛的研究人员使用，并且可以推广到其他单体支架。
