DABCO-based ionic liquid, 1-butyl-4-aza-1-azaniabicyclo[2.2.2]octane hydroxide, has been used as an efficient catalyst for Henry reaction of various carbonyl compounds with nitroalkanes affording very high yields within a short duration. This method is very simple, clean and avoids hazardous organic solvents. The catalyst can be easily recovered and recycled several times.
