Synergistic effect of bimetallic PdAu nanocrystals on oxidative alkyne homocoupling

Abstract

Bimetallic PdAu nanocrystals with different component ratios were obtained to investigate alkyne homocoupling. We found that the synergistic effect of Pd and Au plays an important role in the reaction. Alkynes with a variety of substituent groups could efficiently be converted into the corresponding 1,3-diynes through oxidative coupling.
