Acridinedione as selective flouride ion chemosensor: a detailed spectroscopic and quantum mechanical investigation
to be highly selective chemosensors for fluorideions only. To investigate in detail the mechanism of selective fluorideion sensing, detailed spectroscopic studies were carried out using UV-visible, fluorescence and 1H NMR spectroscopy. Fluoride mediated (NH) proton abstraction of acridinedione was found to be responsible for the observed selective fluorideion sensing. Quantum mechanical computational

Melamine-formaldehyde resin supported H<sup>+</sup>-catalyzed three-component synthesis of 1,8-dioxo-decahydroacridine derivatives in water and under solvent-free conditions
Abstract A convenient and practical synthesis of 1,8-dioxo-decahydroacridine derivatives using various aldehydes, 5,5-dimethyl-1,3-cyclohexanedione and thiourea in water, was successfully carried out in the presence of melamine-formaldehyde resin supported H+ (MFRH) as a catalyst. Undersolvent-freeconditions, rapid and efficientsynthesis of 1,8-dioxo-decahydroacridine and N-substituted 1,8-dioxo-decahydroacridine
