Synthesis of Arylidene (thio)barbituric Acid Derivatives using Bentonite as a Natural and Reusable Catalyst in Green Media
Known as a Lewis acid which acts as a natural catalyst, bentonite can be used to produce several arylidene (thio) barbituric acid derivatives through conducting a Knoevenagel reaction between aromatic aldehydes and (thio) barbituric acid. Water is considered as the medium for this reaction and the results are at arange of good to excellent over a reasonable reaction time. This method i...
متن کاملOxidation of allylic and benzylic alcohols to aldehydes and carboxylic acids.
An oxidation of allylic and benzylic alcohols to the corresponding carboxylic acids is effected by merging a Cu-catalyzed oxidation using O2 as a terminal oxidant with a subsequent chlorite oxidation (Lindgren oxidation). The protocol was optimized to obtain pure products without chromatography or crystallization. Interception at the aldehyde stage allowed for Z/E-isomerization, thus rendering ...
متن کاملMild and Efficient Oxidation of Alcohols with NaIO4 Catalyzed by a Manganese Porphyrin-polyoxometalate Hybrid Material
Efficient and selective oxidation of alcohols with NaIO4 catalyzed by an organic-inorganic hybrid material in which manganese(III)5,10,15,20-tetrakis(4-aminophenyl)porphyrin chloride, MnIII(TAPP)Cl, is covalently linked to a Lindqvist structure of polyoxometalate, Mo6O192-, at room temperature is reported. The effect of various parameters such as catalyst amount, solvent and oxidant were studie...
متن کاملPreparation and characterization of PVC/NiFe2O4/Fe2O3 composite: Catalytic activity for synthesis of Arylidene Barbituric acid derivatives
PVC/NiFe2O4/Fe2O3 compositewas successfully synthesized and characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray powder diffraction (XRD), and scanning electron microscopy (SEM). Also, the catalytic activity of PVC/NiFe2O4/Fe2O3 has been considered in the synthesis of two arylidene barbitu...
متن کاملOxidation of benzylic alcohols with molecular oxygen catalyzed by Cu3/2[PMo12O40]/SiO2
The aerobic oxidation of alcohols was efficiently completed in high conversion and selectivity using Cu3/2[PMo12O40]/SiO2 as catalyst under mild reaction condition. This reaction provides a new environmentally friendly rout to the conversion of alcoholic function to carbonyl groups.
