In this paper, a new palladium grafted mesoporous organic polymer catalyst has been synthesized through the reaction of palladium(II) acetate with mesophorous poly-triallylamine (MPTA-1) in methanol.Abstract:
A new palladium grafted mesoporous organic polymer catalyst has been synthesized through the reaction of palladium(II) acetate with mesoporous poly-triallylamine (MPTA-1) in methanol. Powder XRD, HR TEM, FE SEM-EDS, AAS, UV–vis spectroscopic tools are employed to characterize this supported palladium catalyst Pd–MPTA-1. The Heck coupling reactions between a series of aryl halides and alkenes have afforded the corresponding C–C coupling products in good yield over this Pd-catalyst using water as reaction medium. This protocol provides a simple strategy for the generation of a variety of new C–C bonds by using this recyclable heterogeneous catalyst under environmentally benign conditions.read more
