GREEN SYNTHESIS OF 2-AMINO-3-CYANO-4H-CHROMENES IN WATER USING NANO SILICA-BONDED 5-N-PROPYL-OCTAHYDRO-PYRTMIDO[1,2-4]AZEPINIUM CHLORIDE AS AN EFFECTIVE AND REUSABLE NANO CATALYST
Nano silica-bonded 5-n-propyl-octahydro-pyrimido[1,2-a]azepinium chloride (NSB-DBU) is reported as an highly efficient and recyclable nano catalyst for the preparation of 4H-chromene derivatives in aqueous media. This synthetic method offers a simple, mild and time-saving method under entirely green and environmentally friendly conditions.
