title: Nano PdAu Bimetallic Alloy as an Effective Catalyst for the Buchwald-Hartwig Reaction.
abstract: It is highly challenging but desirable to develop efficient heterogeneous catalysts for C-Cl bond activation in coupling reactions. Here, we succeeded in synthesizing bimetallic Pd-Au nanoparticles through a convenient one-pot wet chemical route. The composition and alloyed structure of the as-prepared nanoparticles were fully characterized. We have evaluated the catalytic activity of these Pd-Au alloy catalysts in Buchwald-Hartwig reactions of aryl chlorides. The excellent catalytic activity of the as-obtained Pd-Au nanoparticles indicates that exploiting the catalytic power of nano-alloy catalysts could enable effective C-Cl bond activation suitable for cross-coupling reactions.
