Then, the catalytic activity of these nanoparticles as magnetic recyclable nanocatalyst was explored for the one-pot three-component synthesis of quinolin-5-one, chromene-3-carbonitrile and phthalazine-5,10-dione derivatives. The reactions proceeded smoothly to provide the respective products in excellent yields under green conditions. Facile preparation of the catalyst, high yields of the products, low reaction times, and use of water as green solvent are the main advantages of the present protocol. Moreover, the catalyst can be easily separated from the reaction mixture in a magnetic field, recycled and reused for six consecutive fresh runs without considerable loss of catalytic activity.

Phenyl sulfonic acid functionalized mesoporous SBA-15 silica (SBA-15-Ph-SO3H) was prepared through the silanization of activated mesoporous SBA-15 with diphenyldichlorosilane (DPCS) followed by silylation and sulfonation, and characterized by XRD, FT-IR, nitrogen adsorption analyses, BET theory and TEM. The sulfonic acid groups anchored to the silica surface of the pore walls were resistant to leaching in organic and aqueous solutions under mild conditions. This catalyst was found to be a recyclable heterogeneous catalyst for the rapid and efficient synthesis of various 2H-indazolo[2,1-b]phthalazine-triones and triazolo [1,2-a]indazole-triones. Also, this silylated mesoporous material containing phenylsulfonic acid groups has a greater stability of the sulfonic acid surface toward water than that of silica sulfuric acid (SSA) and sulfonated SBA-15.
