[BMIm]BF4-LiCl: An effective catalytic system for the synthesis of pyrano[3,2-c]chromene and pyrano[4,3-b]pyrone derivatives
نویسندگان
چکیده مقاله:
An efficient and green method for the synthesis of pyrano[3,2-c]chromene or pyrano[4,3-b]pyrone derivatives is described by using a three-component condensation process of malononitrile, aldehyde, and 4-hydroxycoumarine or 4-hydroxypyrone in [BMIm]BF4-LiCl as an ionic liquid.

A homogeneous ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate doped with LiCl ([BMIm]BF4-LiCl) was found as catalyst solvents for the synthesis of dicoumarols by the condensation of 4-hydroxycoumarin and aldehyde at 80 ˚C. In this field, several types of aromatic aldehyde, containing electron-withdrawing groups as well as electron-donating groups, were rapidly changed to the correspo...

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
