Abstract

Abstract The acidic functionalized ionic liquid 1-(4-sulfonic group) butyl-3-methylpyrazine tetrafluoroborate (abbreviated as [4-sulfbmpyrazine][BF4]) was employed as the catalyst of the condensation of aromatic aldehyde and diols. The optimized condition was as follows: aromatic aldehyde (0.20 mol), diols (0.30 mol) and [4-sulfbmpyrazine][BF4](0.60 g) were refluxed in cyclohexane (10.00 mL) for 1 h. A series of aromatic aldehydes were studied ...
