A general protocol for the palladium-catalyzed carbonylation of aryl tosylates and mesylates to form esters has been developed using a catalyst system derived from Pd(OAc)2 and the bulky, bidentate dcpp ligand. The system operates under mild conditions: atmospheric CO pressure and temperatures of 80-110 degrees C. A broad substrate scope has been demonstrated allowing carbonylation of electron-rich
已经使用衍生自 Pd(OAc)2 和庞大的双齿 dcpp 配体的催化剂系统开发了钯催化的甲苯磺酸芳基酯和甲磺酸酯羰基化形成酯的通用方案。该系统在温和的条件下运行:大气 CO 压力和 80-110 摄氏度的温度。 广泛的底物范围已被证明允许富电子、缺电子和杂环甲苯磺酸酯和甲磺酸酯羰基化,反应显示出广泛的官能团宽容。
