Abstract :
A new Schiff base catalyst (Pd(II) chemically mounted on the cellulose nanocrystals surface (CNCAPTESISPd) was developed for Ulmann and Suzuki crosscoupling reactions. The catalyst was applied for Ulmann reaction using s series of aryl halide and phenol derivatives in DMSO and preparation of biaryls via Suzuki CC reactions between aryl halides and phenyl boronic acid. The Catalyst was characterized by FTIR, XRD, SEM, ICPAES and TGA techniques. The catalyst demonstrated high reaction efficiency with more than 90% reaction yield. The catalyst indicated good performance after several times recovery and reuse.
