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.
在铑/Xantphos 催化剂和 DABCO 的存在下,芳基氰化物与二硼反应通过碳-氰基键断裂提供芳基硼酸酯。这种前所未有的硼铑物种反应模式允许在合成后期区域选择性地引入硼基。
