Nano-colloidal silica-tethered polyhedral oligomeric silsesquioxanes with eight branches of 3-aminopropyltriethoxysilane as high performance catalyst for the preparation of furan-2(5H)-ones
An efficient and rapid method for the synthesis of 3,4,5-substituted furan-2 (5H)-ones has been achieved through a three-component reaction of aniline, dialkyl acetylenedicarboxylate, and aromatic aldehydes using nano-colloidal silica-tethered polyhedral oligomeric silsesquioxanes with eight branches of 3-aminopropyltriethoxysilane (nano-colloidal silica @APTPOSS) as a superior catalyst under m...
متن کاملTheoretical Studies of Solvent Effects on the Electronic Properties of 1, 3-Bis [(Furan-2-yl) Methylene] Urea and Thiourea
The synthesis and characterization of 1, 3-bis [(furan-2-yl) methylene] urea (BFMU) and 1, 3-bis [furan-2-yl) methylene] thiourea (BFMT) have been reported by our research team. The effects of solvents polarity on their electronic transition energies (HOMO-LUMO) and associated qualitative structure activity relationship parameters (i.e. log P, ionization energies and global hardness) were inves...
متن کاملLiquid-Liquid Extraction Study of Sodium and Potassium Ions by a Series of Non Cyclic Ionophores Composed of Furan Units
A new series of noncyclic ionophores containing two to four furan units (Ia to IIIb) i.e. 1,1-difurylethane (Ia), 2,5-bis(methylfurfuryl)furan (IIa) and 1,1’ ethyledenebis[5-(methylfurfuryl)furan] (IIIa), 2,2-difurylpropane (Ib), 2,5-bis (dimethylfurfuryl)furan(IIb), 2,2’-isopropylidenebis[5-(dimethylfurfuryl)furan] (IIIb) have been synthesized by the condensation of furan with acetaldehyde and...
متن کاملMaltose as a green catalyst for the synthesis of 3,4,5-substituted furan-2(5H) ones in water
Maltose as an efficient, available, cheap and eco-friendly catalyst has been applied for the synthesis of 3,4,5-substituted furan-2(5H)one derivatives via a one-pot three-component reaction of arylamines, aromatic aldehydes and dialkyl acetylenedicarboxylates in water. This method has notable advantages in terms of simple workup, no need for column chromatography, short reaction time and high y...
