Fenger, Isabelle published the artcileReusable polymer-supported palladium catalysts: an alternative to tetrakis(triphenylphosphine)palladium in the Suzuki cross-coupling reaction, Recommanded Product: 5-Nitro-2-phenylpyridine, the publication is Tetrahedron Letters (1998), 39(24), 4287-4290, database is CAplus.
The Suzuki cross-coupling reaction of a boronic acid and a bromoarom. compound requires palladium catalysis. Almost identical yields were obtained under the usual conditions, with 30 mequivalent of Pd(PPh3)4, and with 2 mequiv of a polymer-supported catalyst, which was easily prepared in two steps from Merrifield polymer. Recovery and reuse of the catalyst is easy, and only 0.60% of the initial amount of palladium is lost during a reaction.
