| Research Abstract |
Owing to increasing environmental concerns about harmful and resource-consuming solvent waste, the chemistry of organic transformations in water is presently undergoing very rapid growth. On the other hand, development of immobilized reagents has been attracting significant interest for their practical advantages. There is good reason to believe that immobilized catalysts exhibiting high catalytic activity in aqueous media offer a viable clean alternative to more traditional methods of accomplishing many organic reactions. We have examined design and preparation of amphiphilic resin-supported triarylphosphine-palladium complexes bound to a polyethylene glycol-polystyrenegraft copolymer (PEG-PS resin) which exhibit high catalytic activity in allylic substitution reactions of allyl acetates with various nucleophiles in aqueous media under mild reaction conditions. As a part of our efforts to develop the wide utility of these catalysts, the palladium-catalyzed cross-coupling reaction and palladium-catalyzed hydroxycarbonylation in water were also successfully examined.
