A simple, metal-free protocol for unsymmetrical biaryl coupling using H5IO6 is reported. H5IO6 was evaluated for a novel application in the oxidative cross-coupling of phenol-arene, phenol-phenol, and phenol-naphthol compounds. In this work, most of the couplings were completed within 30 min at ambient temperature. 30 coupling products were conveniently obtained using only 0.5 equivalent of H5IO6 in
据报道,使用H 5 IO 6进行不对称联芳基偶联的简单,不含
金属的方案。评价了H 5 IO 6在
苯酚-
芳烃,
苯酚-
苯酚和
苯酚-
萘酚化合物的氧化交叉偶联中的新应用。在这项工作中,大多数联轴器是在环境温度下30分钟内完成的。仅在HFIP中使用0.5当量的H 5 IO 6即可方便地获得30种偶联产物。提出了发生转化的机制。
