Abstract
A polymer-supported terpyridine palladium complex has been prepared. The complex was found to promote the transfer reduction of aryl chlorides with potassium formate in seawater. The terpyridine ligand was prepared from 4-methoxycarbonylbenzaldehyde, 2-acetylpyridine, and NH4OAc according to reported procedures [7-8]. The terpyridine ligand was immobilized on a polystyrene–polyethylene glycol (PS–PEG) resin, and the complexation of the PS–PEG–terpyridine ligand with Pd(II) provided the PS–PEG–terpyridine–Pd(II) complex. The polymeric catalysts showed high catalytic activity and high reusability for the transfer reduction in seawater.
