Pd-based nanocatalysts prepared through immobilization on nanocarbon materials and subsequent pyrolysis can efficiently catalyze the oxidative Heck reaction of tetrafluoropropylene using H(2)O(2) as oxidant, yielding (Z)-beta-fluoro-beta-(trifluoromethyl)styrenes with high yield and selectivity that remain stable after multiple reaction cycles.
Pd-based nanocatalysts were prepared through immobilization of Pd(OAc)(2)/phenanthroline on nanocarbon materials and subsequent pyrolysis. The catalysts were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and electron microscopy (TEM). Pd-based nanocatalysts can efficiently catalyze the oxidative Heck reaction of tetrafluoropropylene by using H(2)O(2)as a green oxidant and generate (Z)-beta-fluoro-beta-(trifluoromethyl)styrenes in excellent yield. The yield andZ/Eselectivity of the titled reaction remained higher than 90% after four reaction cycles.
