Abstract:

Palladium nanoparticlessupported in afeather keratin matrix were efficient catalyst for the coupling reactions of aryl bromides with arylboronic acid in aqueous medium under mild reaction conditions. The biopolymer-based catalyst demonstrated excellent activity for substrates with a wide range of functional groups. The product biaryls were precipitated from the reaction mixture with good to excellent yields and purities. The catalyst was recovered from the reaction solution easily by simple filtration, and can be reused at least seven times.
