ABSTRACT A new heterogeneous cellulose tagged triphenylphosphine (Cell‐OPPh 3 ) was synthesized and subsequently coordinated with Pd(OAc) 2 to form a cellulose‐supported triphenylphosphine palladium complex (Cell‐OPPh 3 ‐Pd). Cell‐OPPh 3 and the corresponding palladium complex were fully characterized by TGA, SEM, TEM, and NMR analysis. Results of catalytic activity experiments indicate that the Cell‐OPPh 3 ‐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. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015 , 132 , 41427.
