[BMIm]BF4-LiCl as an effective catalytic system for the synthesis of dicoumarols

Seyyedeh Cobra Azimi; Kurosh Rad-Moghadam

Volume 3, Issue 4, pp. 283-387, Serial No. 9 , October 2015, , Pages 356-366

Abstract
  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 ...  Read More
