Benzyl ammonium ethoxy silica hydrogen sulfate (BAESHS): A highly efficient heterogeneous nanocatalyst for green synthesis of pyrano[۲,۳-d]pyrimidines

BAESHS was synthesized, characterized, and its catalytic activity was studied in the green synthesis of pyrano[۲,۳-d]pyrimidines. The products were efficiently prepared via three-component reaction of malononitrile, barbituric acid, and aldehydes in the presence of BAESHS in water. The characterization of BAESHS was achieved using XRD, EDX, BET, FE-SEM, FT-IR, DLS, and TGA.
