Chalcones in the synthesis of heterocyclic compounds: pyrazoles, flavans and pyrimidines

Abstract: This study was aimed at the synthesis of a library of heterocyclic compounds. The initial reactions involved the condensation of substituted acetophenones with benzaldehyde derivatives in either ethanolic solution of sodium hydroxide or by grinding method to yield chalcones. The percentage yield of the products was substantially higher by grinding method compared to that of ethanolic NaOH conventional method. It is noteworthy that the grinding technique is an environmentally f...

The effect of substituents on the stability and fragmentation of para benzoquinone molecular anion

Abstract: Quinones form a large group of organic compounds with various applications in industry, biological systems, and pharmacology. They can capture an electron with kinetic energy exceeding zero and keep it for a longer time. The principal structure responsible for electron capturing in quinones is the para-benzoquinone, PBQ. Several studies have been carried out on PBQ and its molecular anion, but less attention has been paid to its derivatives upon capturing an electron. As such,...
