4. Casos práticos de utilização
Case 1: Suzuki-Miyaura Cross-Coupling Reaction
Step-by-Step:
- Mix 2,2′-Biphenol (0.1 mmol) with Pd(OAc)2 in anhydrous THF.
- Add aryl halide (1.2 eq) and boronic acid (1.5 eq) under N2.
- Heat at 80°C for 12 hours; yield reaches 92% with 99% selectivity.
Caso 2: Estabilização de polímeros
Processo: Add 0.5% w/w 2,2′-Biphenol to polypropylene during extrusion. Reduces thermal degradation by 70% at 200°C.
