▎ 摘　　要

In this study, the organosilane-functionalized graphene oxide as a stabilizer was prepared by a facile one-step silylation approach. [Cu(PPh3)(3)Cl] complex was successfully immobilized onto the graphene oxide surface through coordination interaction with organosilane ligand spacers. The supported catalyst showed enhanced catalytic performance toward Sonogashira reaction of aryl halides with phenylacetylene in water solvent compared with the homogeneous analogues, and it could be readily recycled and reused several times without discernible loss of its activity.
