Abstract

In this paper, we have reported the synthesis and characterization of new magnetic bionanocatalyst based on chitosan and investigated their catalytic activity in the C-C bond formation reaction. To increase the stability of chitosan, chitosan oxide and starch oxide biopolymers were used for the covalent linking between chitosan chains and formation of Schiff base between amine groups of chitosan and carbonyl functional groups of chitosan oxide and starch oxide. Then, the imine bonds were reduced to prevent their possible hydrolysis. In order to catalyst simple separation of reaction mixture, biopolymer support was magnetized with iron oxide nanoparticle addition. Then, palladium chloride was immobilized on this support and the efficiency of the obtained nanocatalyst was investigated in the Suzuki coupling reaction. The biphenyl products were synthesized under optimized at the short reaction times with excellent yields in water as green solvent. After the reaction cycle, these catalysts were recovered by using a magnetic field and directly reused for several times without significant loss of its activity.
