| Popis: | Sulphated tin oxide-fly ash peony flower like nano catalyst was employed for the synthesis of some E-pyrenyl enones by microwave irradiated Aldol condensation of various substituted acetophenones and 1-pyrenaldehyde under solvent-free conditions. About 80% yields were obtained in this protocol. Catalytic character of SO42--SnO2-fly ash peony flower was investigated using obtained yield and reusability. These E-pyrenyl enones were characterized by their melting points, CHN analysis and spectroscopic data. Also, the influence of the solvents on the yield was investigated. |
