An FT-EPR investigation of the anomalous CIDEP in photoreactions of chromone and chromone-2-carboxylic acid with alcohol induced by hydrochloric acid
(Elsevier Science Sa, 2006-12)
The anomalous net absorptive CIDEP spectra observed in the photoinduced hydrogen abstraction reaction of chromone (CR) and chromone-2-carboxylic acid (CRCA) from 2-propanol with addition of hydrochloric acid (HCl) were ...
Trifluoromethanesulfonic acid supported on carbon used as catalysts in the synthesis of flavones and chromones
(Elsevier Science, 2009-01)
Solid acid catalysts based on trifluoromethanesulfonic acid (TFMS) were synthesized using two different activated carbons as supports. They were characterized by FT-IR, DTA-TGA and BET, and their acidity was measured by ...
Green and efficient synthesis of flavones and chromones using heteropolyacids as catalyst in glycerol
(Bentham Science Publishers, 2018-04-22)
Organic solvents are required to carry out most organic transformations, which cause environmental pollution because of their low volatility. Glycerol, a side product obtained from biodiesel production, has emerged as a ...
