Cellulose Schiff base-supported Pd(II): An efficient heterogeneous catalyst for Suzuki Miyaura cross-coupling

Cellulose-supported Schiff base Pd(II) complex [(Cell-Sc-Pd(II))] has been designed and synthesized by multistep approach. (Cell-Sc-Pd(II)) was characterized by techniques, viz . FT-IR, XRD, XPS, EDS, FE-SEM and TGA. Catalytic activity of (Cell-Sc-Pd(II)) is explored for Suzuki Miyaura cross-coupling of phenyl boronic acid and aryl halides. Special features of present method are high TONs and TOFs, low catalyst loading (0.0016 mol %), reusability of the catalyst at least for five times and synthesis of novel biphenyl derivatives of xanthenes.
