摘要:
Polyrner supported palladium complexes, containing a pyridyl bis N-heterocyclic carbene ligand system derived from isonicotinic acid, provide highly stable catalysts for Heck and Suzuki cross coupling reactions. These heterogenous catalysts can be recycled greater than or equal to 14 times with no loss of activity. (C) 2004 Published by Elsevier Ltd.
