摘要：

A simple, convenient and green protocol has been developed for the synthesis of cellulose supported Pd(0) nanoparticles (NPs) using hearth wood extract of Artocarpus lakoocha Roxb-as a bioreductant. Novel one-step method for the isolation of active bioreductant oxyresveratrol (2,3', 4, 5'-tetrahydroxy-trans-stilbene) present in the hearth wood extract of A. lakoocha Roxb is also disclosed. Synthesized cellulose supported Pd(0) NPs have been used as an efficient catalyst for Suzuki and Heck coupling reactions in water under microwave irradiation. The prepared Pd(0) NPs were characterized by Ultraviolet-visible (UV-vis), Fourier transform-infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and Transmission electron microscopy (TEM). The catalyst can be recycled up-to ten times without losing its activity significantly. (C) 2015 Elsevier B.V. All rights reserved.
