Conditions for the palladium-catalyzed direct arylation of a wide range of heterocycles with aryl bromides are reported. Those conditions employ a stoichiometric ratio of both coupling partners, as well as a substoichiometric quantity of pivalic acid, which results in significantly faster reactions. An evaluation of the influence of the nature of the aryl halide has also been carried out.
报道了各种杂环与芳基溴化物进行钯催化的直接芳基化的条件。这些条件使用了两个偶联配偶体的化学计量比以及新戊酸的亚化学计量量,这导致反应明显加快。还已经进行了对芳基卤化物的性质的影响的评估。
