An efficient synthesis of α,α'-benzylidene bis(4-hydroxycoumarin) derivatives catalyzed by Tl2O3 nanoparticles

In this work, we attempted to synthesize thallium (III) oxide nano structures by direct thermal decomposition using thallium I phenylsuccinic acid coordination polymer [Tl(PsucH)]n as a precursor. Also, Tl2O3 nanoparticles have been characterized by scanning electron microscopy (SEM), X-Ray powder diffraction (XRD) and IR spectroscopy and then we report a simple and efficient method for the syn...

Synthesis of quinazolines via CuO nanoparticles catalyzed aerobic oxidative coupling of aromatic alcohols and amidines.

CuO nanoparticles were found to be efficient catalysts for the synthesis of quinazoline derivatives; twenty-four products were obtained with good to excellent yields via reaction of N-arylamidines and aromatic aldehydes or benzyl alcohol in air. Neither a base nor an organic oxidant was necessary, and CuO nanoparticles can be recycled without a significant decrease in catalytic activity.
