The first example of catalytic thiocarbonylation of aryl iodides using CO₂ has been achieved employing a combination of PdCl₂ and carbazole-derived phosphine ligands. Under mild conditions, a broad scope of aryl iodides were converted to the desired thioester products in the presence of aryl or alkyl thiols (33 examples, up to 96% yields). The choice of metal, ligands, and reductant were crucial for high efficiency and chemoselectivity. Moreover, this strategy provided an effective method for the late-stage functionalization of biorelevant molecules.

使用 CO2 的钯催化芳基碘化物的硫代羰基化反应

_{使用CO 2}催化芳基碘化物硫代羰基化的第一个例子是使用PdCl ₂和咔唑衍生的膦配体的组合实现的。在温和条件下，在芳基或烷基硫醇存在下，多种芳基碘化物转化为所需的硫酯产物（33 个例子，产率高达 96%）。金属、配体和还原剂的选择对于高效率和化学选择性至关重要。此外，该策略为生物相关分子的后期功能化提供了有效的方法。
