Biopolymer–metal complex wool–Pd as a highly active catalyst for Suzuki reaction in water
Co-reporter:Heng-chang Ma, Wei Cao, Zhi-kang Bao and Zi-Qiang Lei  
Catalysis Science & Technology 2012 vol. 2(Issue 11) pp:2291-2296

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.
