چکیده:

Phenyl sulfonic acid functionalized mesoporous SBA-15 silica (SBA-15-Ph-SO3H) was prepared through the silanization of activatedmesoporous SBA-15 with diphenyldichlorosilane (DPCS) followed with silylation and sulfonation. The sulfonic groups anchored to the silica surface of the pore walls are resistant to leaching in organic and aqueous solutions under mild conditions. This catalyst is found to be a recyclable heterogeneous catalyst for the rapid and efficient synthesis of various 2H-indazolo[2,1-b]phthalazine-triones.
