Use of Polymer-Supported Terpyridine-Palladium Complex for Mizoroki-Heck Reaction in Water under Aerobic Conditions

Abstract

  A novel heterogeneous transition-metal catalyst, a polymer-supported terpyridine-palladium(II) complex, was prepared from 4-methoxycarbonylbenzaldehyde, 2-acetylpyridine, NH₄OAc according to the reported procedures and found to promote the Mizoroki-Heck reaction in water between aryl halides and styrenes under aerobic conditions with high to excellent yield. The catalyst was recovered and reused several times without loss of catalytic activity.
