Biopolymer-metal complex wool-Pd as a highly active catalyst for Suzuki reaction in water

A heterogeneous biopolymer complex wool-Pd catalyst has been applied in water-mediated coupling reactions of aryl iodides and bromides with arylboronic acid. The results showed that the reactions could be conducted in neat water under atmospheric conditions with water-insoluble or even solid aryl halides. More importantly, the catalyst system has the advantages of excellent yields, environmental friendliness, and catalyst recyclability.
