Abstract
In this study, a polymer-supported terpyridine–palladium complex was prepared and found to promote the transfer reduction of aryl chlorides with potassium formate in water. Thus, terpyridine ligand was prepared from 4-methoxycarbonylbenzaldehyde, 2-acetylpyridine, NH4OAc according to the reported procedures. Immobilization of terpyridine ligand onto a PS-PEG resin took place and the complexation of PS-PEG-terpyridine ligand with Pd(II) underwent to give PS-PEG-terpyridine-Pd(II) complex. The polymeric catalysts showed high catalytic activity and high reusability for the transfer reduction in water.
