Abstract
A number of β-hydroxy-ketone derivatives bearing a coumarin unit have been synthesised by the Reformatsky reaction of formyl coumarin and α-bromoacetophenone in an ionic liquid (1-butyl-3-methylimidazolium chloride, [Bmim]Cl). The recovered ionic liquid can be reused at least five times without a significant reduction in yield. This procedure is green, mild and environmentally benign.
