3-diiodinated 1,4-dihydrothiophenes and naphthalenes has been developed via the electrophilic iodocyclization of various aryl propargyl alcohols. The resulting product 2p can be used for the synthesis of a rubrene intermediate.
dehydration polymerization of propargylicalcohols. Coppercatalysis allows for efficient in situ generation of [n]cumulenes (n = 3, 5) by a soft deprotonation/β-elimination pathway and subsequent polymerization via organocopper species. Alkyne polymers (Mn up to 36.2 kg/mol) were produced with high efficiency (up to 95% yield) and excellent functional group tolerance. One-pot synthesis of semiconducting head-to-head
在这里,我们报告了一种铜催化的炔丙醇形式脱水聚合。铜催化允许通过软去质子化/β-消除途径有效地原位生成 [ n ]cumulenes ( n = 3, 5),然后通过有机铜物种进行聚合。炔烃聚合物(Mn高达36.2 kg/mol)的生产效率高(产率高达 95%)和优异的官能团耐受性。通过聚合-异构化序列证明了半导体头对头聚苯乙炔的一锅法合成。
