A concise and efficiently route for the synthesis of 3-substituted benzofurans via the intramolecular Heck reaction of bromoaryl 3-phenylallyl ethers has been developed. This simple and highly efficient palladium nanoparticles-catalyzed system showed good catalytic activity. The desired products were affored in good to high yields (45%~96%).

Key words: benzofuran, intramolecular Heck reaction, palladium nanoparticles
