Ligand-Free PdCl2-Catalyzed Heck Reaction of Arylboronic Acids and Olefins under Reusable TBAB/H2O Conditions
摘要:
A novel method was developed for Heck reaction of olefins and arylboronic acids using a ligand-free PdCl2 catalyst to afford the coupling products with excellent regio- and stereoselectivity. It is noteworthy that the PdCl2/CuSO4/K2CO3/TBAB/H2O system can be recovered and used for three cycles directly.
