摘要

A new heterogeneous cellulose tagged triphenylphosphine (Cell-OPPh3) was synthesized and subsequently coordinated with Pd(OAc)(2) to form a cellulose-supported triphenylphosphine palladium complex (Cell-OPPh3-Pd). Cell-OPPh3 and the corresponding palladium complex were fully characterized by TGA, SEM, TEM, and NMR analysis. Results of catalytic activity experiments indicate that the Cell-OPPh3-Pd complex can efficiently catalyze Suzuki-Miyaura cross-coupling reactions of aryl halides with arylboronic acids at mild reaction conditions. The coupling products can be obtained in good to excellent yields (up to 98%). The work-up procedure is simple and the catalyst could be easily recovered by filtration, and then reused in next run.
