Herein, we describe the synthesis and Stille cross-coupling reactions of 2-(tributylstannyl)- and 2,5-bis(trimethylstannyl)tellurophene. The reactions were most optimal when using aryl iodides as coupling partners, and a mixed catalyst system consisting of tetrakis(triphenylphosphine)palladium(0) and copper(I) iodide, together with cesium fluoride as additive, in N,N-dimethylformamide. This is the
在本文中,我们描述了2-(三丁基锡烷基)-和2,5-双(三甲基锡烷基)tellurophene的合成和Stille交叉偶联反应。当使用芳基碘化物作为偶联伙伴,以及在N,N-二甲基甲酰胺中由四(三苯基膦)钯(0)和碘化铜(I)以及氟化铯作为添加剂组成的混合催化剂体系时,反应是最佳的。这是第一个报道的合成和使用锡烷基化的碲代吩用于交叉偶联反应。 碲代吩-斯蒂勒反应-交叉偶联-钯-杂环
