Metal-free alternative: Rethinking coupling methods for more sustainable organic synthesis
Coupling reactions are among the most transformative tools in organic chemistry, enabling the formation of crucial chemical bonds in pharmaceuticals, agrochemicals, and advanced materials. Since their introduction, they have been one of the backbones of modern organic synthesis. However, these methods have long relied on environmentally taxing transition metal catalysts, such as palladium, which are often scarce, costly, and generate unwanted byproducts.
