The synthesis of benzo[f]chromeno[3,4-b]quinoline-6-ones has been achieved via one-pot three-component reaction from substituted aromatic aldehydes, 3-aminocoumarins, and 2-naphthol in n-butanol using 10 mol % of ...

In this work, a simple and facile method for the preparation of tribromo melamine (TBM or melamine‐Br3) as an environmentally friendly homogeneous catalyst is described as it is used for the one-pot synthesis ...

Transition metals (ferrous ammonium sulphate and ammonium nickel sulphate) complexes have been proved to be efficient catalysts for transesterification of β-keto esters with various aromatic and hetero aromatic ...

Aniline, phenol, and their derivatives are widely used in industrial chemicals that consequently have a high potential for environmental pollution. Genetic algorithm and partial least square (GA-PLS), kernel partial least ...

A basic phase-transfer catalyst ([PEG(mim)2][OH]2) was prepared from the reaction of polyethylene glycol-bis(N-methylimidazolium) dibromide and sodium hydroxide dissolved in water at ambient ...

ZnFe2O4 as a novel nanoparticle was prepared and characterized using x-ray diffraction (XRD) analysis, energy dispersive x-ray (EDX), vibrating sample magnetometry (VSM), and fourier-transform infrared ...

Oxazole derivatives were prepared via multicomponent reaction of carbohydrazide, dialkyl acetylenedicarboxylate and ketone at room temperature under solvent-free conditions in good yields.  One of the alternative ...
