Abstract The catalytic efficacy of different cesium salts of 12-tungstophosphoric acid as nanocatalysts was checked in Claisen-Schmidt condensation of aldehydes and ketones under solvent-free conditions to […]

ABSTRACT Biologically active chalcones were synthesized via Claisen-Schmidt condensation of aldehydes with different ketones in solvent-free conditions using H5PMo10V2O40 supported on SiO2 as a reusable heterogeneous […]

Abstract   A keto-enol equilibrium between two tautomers of the 1,5-bis(2′-pyridyl)pentane-1,3,5-trione (trione) (1) was observed in solution based on 1H and 13C NMR spectroscopy. NMR data shows […]
