4. Casos prácticos

Case 1: Suzuki-Miyaura Cross-Coupling Reaction

Step-by-Step:

1. Mix 2,2′-Biphenol (0.1 mmol) with Pd(OAc)₂ in anhydrous THF.
2. Add aryl halide (1.2 eq) and boronic acid (1.5 eq) under N₂.
3. Heat at 80°C for 12 hours; yield reaches 92% with 99% selectivity.

Caso 2: Estabilización de polímeros

Proceso: Add 0.5% w/w 2,2′-Biphenol to polypropylene during extrusion. Reduces thermal degradation by 70% at 200°C.
