Abstract:

The facile and high yield synthesis of a new series of dibenzophenones in the presence of polyphosphoric acid (PPA) together with their cyclization to corresponding moni and dixanthones are described. The aromatic nucleophilic substitution of these new compounds are also studied.

BiFeO3 Magnetic Nanoparticles: A Novel, Efficient and Reusable Magnetic Catalyst for the Synthesis of Polyhydroquinoline Derivatives

Herein, it has been shown that the bismuth ferrite magnetic nanoparticles (BFO-MNPs) are new, efficient and recyclable catalysts for the synthesis of polyhydroquinoline derivatives by the Hantzsch reaction. The one-pot four-component cyclocondensation reaction of dimedone, aromatic aldehydes, ethyl acetoacetate and ammonium acetate was carried out under solvent-free conditions. The...
