reports a facile and green approach for the synthesis of thiazolidine/oxazolidine derivatives 4(a–u) in excellent yields (92–98%) with high purity. The protocol involves a one-pot three-componentreaction of substituted 1,3-diketones 1(a–g), cyanates 2(a–c) and ethylchloroacetate (3) in ionicliquid [Et3NH][HSO4] under solvent-free conditions. The notable feature of this pathway is that the ionic liquid
reactions of ammonia and alkylamines with sulfuric acid play an important role in aerosol formation and particle growth. However, little is known about the physical and chemical properties of alkylaminium salts of organic acids. In this work we studied the thermal stability and volatility of alkylaminium carboxylate salts of short aliphatic alkylamines with monocarboxylic and dicarboxylic acids. The enthalpy

the highly polarsolvent N,N-dimethylformamide (DMF), precise measurements such as densities (ρ) and ultrasonic sound velocities (u) over the whole composition range have been performed at atmospheric pressure and over wide temperature ranges (25–50 °C). The excess molar volume (VE) and the deviation in isentropic compressibilities (Δκs) were predicted using these temperaturedependence properties

investigate the association of vanadium with physiological substrates in materials capable of exerting anticancer biological activity, pH-specific synthetic chemical reactivity between vanadium and triethyl ammonium acetate/trigonelline in aqueous and mixed organic-aqueous media led to the isolation of three new binarycompositematerials, namely K2[(MeN(+)C5H4COOH)2][V10O28H2]·2H2O (1), [(H2N(+)Me2)4][V
