Abstract
Henry reaction can be accelerated by basic ionic liquid 1-methyl-3-butylimidazolium hydroxide ([bmIm]OH) as catalyst and reaction medium with good yields in short time at room temperature. This strategy is general and works with a broad range of aldehydes. The recovered [bmIm]OH can be recycled with consistent activity.
