Abstract

The performance of Pd(OAc)2, Pd0 dendrimer-encapsulated nanoparticles, and PdII-dendrimer complexes in several Stille reactions in water is compared. The presence of the dendrimer suppresses the formation of homocoupling products and allows catalyst recycling. It is suggested that the reaction catalyzed by DENs occurs via palladium species which are leached from the nanoparticle but which remain coordinated to the dendritic macromolecule.
