Sulfonic acid functionalized SBA-15 nanoporous material (SBA-Pr-SO3H) with a pore size of 6 nm was found to be a green and effective solid acid catalyst in the one-pot synthesis of 2,4,5-trisubstituted and 1,2,4,5-tetrasubstituted imidazoles under solvent-free conditions. SBA-PrSO3H was proved to be a recyclable, green, and highly efficient catalyst which could be easily handled, recovered, and reused several times without significant loss of reactivity.
