Ammonium-type Basic Ionic Liquid; 2-(2-Hydroxyethoxy)ethaneammonium Formate: Promote Green and Efficient Multicomponent Tandem Synthesis of 4H-pyrans and 4H-chromenes

A facile, convenient, green and environmentally benign one-pot three-component synthesis of poly-functionalized 4H-pyrans and 4H-chromenes is described. A basic ionic liquid 2-(2-hydroxyethoxy)ethaneammonium formate was found to be an efficient catalyst or catalytically active solvent for the synthesis of those important classes of heterocyclic compounds.

Reduction of Carbon Dioxide to Formate at Low Overpotential Using a Superbase Ionic Liquid

A new low-energy pathway is reported for the electrochemical reduction of CO2 to formate and syngas at low overpotentials, utilizing a reactive ionic liquid as the solvent. The superbasic tetraalkyl phosphonium ionic liquid [P66614][124Triz] is able to chemisorb CO2 through equimolar binding of CO2 with the 1,2,4-triazole anion. This chemisorbed CO2 can be reduced at silver electrodes at overpo...

Synthesis of TiO2 nanoparticles in pure 2-hydroxyethylammonium formate room temperature ionic liquid and investigation of its photocatalytic properties

TiO2 nanoparticles were synthesized by modified sol—gel method using pure room temperature ionic liquid(RTIL) 2-hydroxyethylammonium formate as a reaction medium. The structure and morphology of TiO2nanoparticles were characterized with X-ray powder diffraction (XRD), BET surface analysis and scanningelectron microscopy (SEM). TiO2 nanoparticles were synthesized in open and closed vessels. The ...

Highly active and selective catalysis of copper diphosphine complexes for the transformation of carbon dioxide into silyl formate.

Copper diphosphine complexes have been found to be highly active and selective homogeneous catalysts for the hydrosilylation of CO2. The structure of the phosphine ligands strongly affects their catalytic activity. Turnover number (TON) reaches 70,000 after 24 hours with 1,2-bis(diisopropylphosphino)benzene as a ligand under 1 atmosphere of CO2. (1)H and (13)C NMR spectra, carried out under the...
