Palladium supported on ethylenediaminetetraacetic acid functionalized cellulose: synthesis, characterization, and its application in carbon–carbon cross-coupling reactions

Through the esterification of cellulose (Cell) with ethylenediaminetetraacetic dianhydride, acid-functionalized (Cell-EDTA) was conveniently obtained. Furtherly a novel and efficient Cell-EDTA-supported palladium catalyst (Pd@Cell-EDTA) easily prepared via coordination Cell-EDTA PdCl2. The as-prepared Pd@Cell-EDTA fully characterized by inductively coupled plasma atomic emission spectrometry, X-ray photoelectron spectroscopy, Fourier transform infrared spectra, energy-dispersive scanning electron microscopy, transmission thermogravimetric analysis derivative techniques. Then successfully exerted as catalysts in Suzuki reactions Sonogashira reactions. Due to interactions carboxylic groups, nitrogen atoms, hydroxyl groups on cellulose, Pd complex showed excellent activity towards these carbon–carbon cross-coupling recycling experiments for model reaction that can be reused at least five times without significant losing its catalytic performance. present cellulose-based offers salient features wide application, activity, good reusability, tolerance broad scope substrate, environmental benign.
