A highly useful, visible-light-driven carboxylation of aryl bromides and chlorides with CO2 was realized using a combination of Pd(OAc)2 as a carboxylation catalyst and Ir(ppy)2(dtbpy)(PF6) as a photoredox catalyst. This carboxylation reaction proceeded in high yields under 1 atm of CO2 with a variety of functionalized aryl bromides and chlorides without the necessity of using stoichiometric metallic
使用 Pd(OAc)2 作为羧化催化剂和 Ir(ppy)2(dtbpy)(PF6) 作为光氧化还原催化剂的组合,实现了非常有用的、可见光驱动的芳基溴化物和氯化物与 CO2 的羧化。该羧化反应在 1 个大气压的 下与各种官能化的芳基溴化物和氯化物以高产率进行,无需使用化学计量的金属还原剂。
