Regio- and stereoselective hydrosilylation of alkynes catalyzed by SiO2 support Pd-Cu bimetallic nanoparticles

Abstract

An efficient, recyclable Pd-Cu bimetallic nanoparticles catalyst has been prepared, which exhibits superior activity and selectivity for the hydrosilylation of internal and terminal alkynes under mild reaction conditions with a low catalyst loading. Distinct enhancement in catalytic performance is observed when compared with traditional monometallic catalysts, and composition of the BMNPs is found to be crucial in both the selectivity and yield. This kind of elevation in catalytic performance can be ascribed to the enrichment of active sites (Pd) on the catalyst surface and a phenomenon collectively referred as “synergistic effects”. The successful application of BMNPs as a catalyst in the alkyne hydrosilylation opens new possibilities for the excavation of the value of bimetallic nanoparticles in catalysts development for sustainable chemistry.
