Suzuki reaction catalyzed by Pd(Ⅱ) anchored on polymer in supercritical carbon dioxide
Palladium chloride anchored on polystyrene modified by 5-amino-1,10-phenanthroline was prepared and used as catalysts for the Suzuki cross-coupling reactions of aryl halide with arylboronic acid in supereritical carbon dioxide without use of organic solvent.The heterogeneous catalyst revealed excellent and recoverable catalytic performance for a wide range of aryl halides substrates.It can be easily separated from the reaction mixture and reused for six recycles without significant loss of catalytic activity.
