Recent Advances in the Application of Chitosan and Chitosan Derivatives as Bio Supported Catalyst in the Cross Coupling Reactions

摘要

The present review article surveys an outline on the most recent efforts and exciting developments (between 2010-2018 years) in the application of chitosan and modified chitosan derivatives as bio support for metal immobilization in the cross coupling reactions. The procedures incorporated in this review comprise metal nanoparticles (Pd, Ni, Cu, Au, Co) or metal ions immobilization on non-modified chitosan, porous chitosan microspheres, chitosan hybrid with other organic and inorganic polymers and functionalized chitosan with different ligands such as amine, amide, thiourea, amino acid, carbene and Schiff base derivatives. Also, in each case, the catalytic efficiency was described in various cross coupling reactions.
