The study of cross-coupling between hexachlorobenzene and phenylboronic acid comprised five Buchwald ligands, from which 2-dicyclohexylphosphino-2′-(dimethylamino)biphenyl (DavePHOS) provided the best conversion. When excess of phenylboronic acid was used, a mixture of isomeric tri-, tetra- and pentaphenyl-substituted derivatives in the ∼10:70:20 ratio was obtained, along with minor amounts of hydrodechlorination
六氯苯和苯基硼酸之间的交叉偶联研究包括五个 Buchwald 配体,其中 2-二环己基膦基-2'-(二甲氨基)联苯 (DavePHOS) 提供了最佳转化率。当使用过量的苯基硼酸时,获得了比例为~10:70:20 的异构三、四和五苯基取代衍生物的混合物,以及少量的加氢脱氯产物。
