An Efficient Solvent-Free Synthesis of Bis(2-Tetrahydrobenzofuranyl)Alkanes Catalyzed by H₂SO₄•SiO₂

Abstract:

A series of bis (2-tetrahydrobenzofuranyl) alkanes in good yield under solvent-free conditions from differently aromatic substituted aldehydes and 3-methyl-6,7-dihydrobenzofuran-4(5H)-one in the presence of H₂SO₄•SiO₂ as catalyst at 90oC. Their structures were characterized by NMR, IR and ESI-MS. The proposed mechanism for the H₂SO₄•SiO₂-catalyzed condensation reaction have been discussed in the work. This versatile approach has the advantages of broad functional group compatibility, short reaction times, simple operation and environmentally benign nature.
