The present study reports the procedure conducted in SBA-15/CCPy/CuI preparation as a new Mesoporous nanocatalyst, whereas melamine bearing pyridine groups on SBA-15 are used to secure CuI catalyst as capping agent. The resultant catalyst was specified by conducting TEM, FESEM, WDX, ICP, and EDS. The SBA-15/CCPy/CuI catalytic behavior was studied to N-arylation of indole, imidazole, pyrazole, benzyl amine, and aniline by coupling reactions of Ullmann-type C-N. Also, the heterogeneous catalyst may simply be recovered via filtration and used again for seven cycles with no considerable loss in activity. The findings revealed the privileges of the present method, including the high product yield, experimental simplicity, low catalyst loading, broad substrate scope, and short reaction times.
