These are used in various industries especially food and pharmaceutical industries, due to their non-toxicity as pH regulators, catalysts and preservatives in food products. In recent years, ionic liquids (ILs) and molten salts (MSs) with acetic acid moieties such as pyridine, imidazole, nano-magnetic Fe3O4 and poly 4-vinylpyridine based salts as Brønsted acidic homogenous and heterogeneous have been used as versatile catalysts for various purposes. In this spotlight, we have reviewed ionic liquids (ILs) and molten salts with acetic acid tags as efficient catalysts for the synthesis of azido alcohols, α-ariloxy alcohols, tetrahydrobenzo[b]pyrans, 2-amino benzo[h]chromene, spiropyran, bis-coumarins, 4,4’-(arylmethylene)-bis(3-methyl-1-phenyl-1H-pyrazol-5-ol)s, naphthodipyrans and amidoalkyl phenols.
