Acoplamiento de Suzuki
ArBr + ArB(OH)2 → Ar–Ar + B(OH)3 + HBr
Descripción general
The Suzuki reaction couples an aryl halide with an aryl boronic acid using a palladium catalyst to form a biaryl product. This cross-coupling reaction proceeds through oxidative addition, transmetalation, and reductive elimination steps. Akira Suzuki shared the 2010 Nobel Prize for this work.
Ejemplo cotidiano
The LCD screens in phones and TVs use organic molecules made by Suzuki coupling for their liquid crystal and OLED materials.
