Chitosan-g-mPEG-supported palladium (0) catalyst for Suzuki cross-coupling reaction in water

A chitosan-g-mTEG (methoxy triethylene glycol)- or mPEG (methoxy polyethylene glycol)-supported palladium (0) catalyst was prepared for the Suzuki cross-coupling reaction in water. The catalyst showed excellent catalytic activity in the Suzuki cross-coupling reaction without additional phase transfer reagents due to the enhanced solubility of the organic substrate by PEG grafting. In addition, the catalyst could be reused up to five times with the catalytic activity being recovered easily after simple manipulations.

A chitosan-g-mPEG-supported palladium (0) catalyst has been developed for the Suzuki cross-coupling reaction in neat water. The catalyst showed good catalytic activity with the function of solubilizing the organic substrates by grafted PEG in the reaction. Also, the catalyst was reused up to five times and easily recovered even though its catalytic activity was somehow decreased during the reaction.Figure optionsDownload as PowerPoint slide
