چکیده
|
Some novel pyrimidine derivatives are prepared via one-pot reaction of triethoxymethane, aromatic ketone and ammonium acetate using catalytic system including nano-magnetic pyridinium- tribromide (TBP-SCMNPs). The synthesized new catalyst was characterized by FE-SEM, EDS, TEM, XRD, and TGA analysis. The highlighting points of using TBP-SCMNPs are easy purification, reusability of the catalyst, good yields of products with short time reactions.
