چکیده مقاله :
Chromenes are very important due to many industrial, pharmaceutical and biological uses. 4H-benzo[h]chromene reaction is one pot multistep reaction. The aim of this research is the synthesis of Ag nanoparticles supported on dendritic fibrous nanosilica (DFNS/Ag) and the synthesis of 4H-benzo[h]chromene derivatives in the presence of DFNS/Ag nano catalyst. Also, the reaction of 4H-benzo[h]chromene was investigated at different temperatures, the amount of catalyst and different solvents. The results showed that the reaction of 4H-benzo[h]chromene in ethanol solvent, temperature of 75℃ and 0.03 g of catalyst had the best efficiency. DFNS/Ag catalyst has a high and efficient contact surface due to its dandelion shape.
