Abstract

5-(N,N-bis-3-(triethoxysilyl) propyl) ureyl- 1,10-phenanthroline was prepared and successively grafted onto mesoporous silica of SBA-15 to get SBA-15 anchored ligand which was then reacted with Cu(I) to get SBA-15 anchored complex as the heterogeneous copper catalyst. This catalyst was characterized by FT-IR, XRD, CHN, AAS, TGA, EDAX, BET, SEM and TEM. The activities of the catalyst were tested in C–N cross-coupling of amides and N–H heterocycle compounds with aryl halides. The catalyst showed high catalytic activities for these crosscoupling reactions providing good to excellent yields of desired products. Moreover, the catalyst can be easily recovered by simple filtration and reused several times without significant loss of its catalytic activity.
