The reaction of aryl cyanides with diboron in the presence of a rhodium/Xantphos catalyst and DABCO affords arylboronic esters via carbon-cyano bond cleavage. This unprecedented mode of reactivity for a borylrhodium species allows the regioselective introduction of a boryl group in a late stage of synthesis.
芳基氰化物与二硼在铑/Xantphos 催化剂和 DABCO 的存在下反应，通过碳氰基键断裂生成芳基硼酸酯。这种铑硼酸物种前所未有的反应模式允许在合成的后期阶段进行区域选择性的硼基引入。
