A highly active, air- and moisture-stable and easily recoverable magnetic-nanoparticle-supported palladium catalyst enables the Suzuki cross-coupling reaction of alkynyl bromides with organoboron derivatives in very good yields in ethanol. The supported palladium catalyst can be recovered and reused up to 16 times without significant loss of catalytic activity.
