This study furnishes an economic and eco-friendly catalyst for organic transformation in sustainable chemistry.Īffrose A, Suresh P, Azath IA, Pitchumani K (2015) Palladium nanoparticles embedded on thiourea-modified chitosan: a green and sustainable heterogeneous catalyst for the Suzuki reaction in water. CPIP complex has also been found to give magnificent results in Suzuki–Miyaura and Heck cross-coupling reactions, and therefore, using this green catalyst, the toxic phosphine ligand can be excluded from cross-coupling reactions. This catalyst shows an excellent activity in the reduction of toxic pollutant nitrobenzene to less toxic aniline.
TG-DSC study suggested that the catalyst is thermally stable up to 300 ☌.
The formed CPIP has been extensively characterized with respect to raw chitosan utilizing methods including FT-IR, pyrolysis GC–MS, XRD, XPS, FE-SEM, EDS, TGA-DTG and DSC. In this work, the modification of chitosan using 2-acetyl pyridine has been used to prepare an intermediate, chitosan pyridyl imine (CPI), in first step and then in second step it is further reacted with Pd(OAc) 2 to develop chitosan pyridyl imine palladium (CPIP) complex catalyst in a very simplistic way.
