A novel method of hydrogenation of aromatic ketones in the ionic liquid [BHEA][HCO2] was developed; this method is more enhanced in terms of flammability and reusability as compared to the conventional method (H2 and Pd/C). The reductive selectivities of aromatic and aliphatic ketones in this method were observed.
