SHATERIAN, H.R.  e  MOHAMMADNIA, M.. Acidic brønsted ionic liquids catalyzed the preparation of 1-((benzo[d]thiazol-2-ylamino)(aryl)-methyl)naphthalen-2-ol derivatives 1-[(1,3-benzothiazol-2-ylamino)(aryl)methyl]-2-naphthol. S.Afr.j.chem. (Online) [online]. 2013, vol.66, pp.00-00. ISSN 1996-840X.

The acidic ionic liquids, triethylammonium hydrogen sulfate ([Et₃NH]HSO₄), 2-pyrrolidonium hydrogen sulfate ([Hnhp]HSO₄), 3-methyl-1-sulfonic acid imidazolium chloride ([Msim]Cl), and 1-methylimidazolium hydrogen sulfate ([Hmim]HSO₄) catalyzed three-component condensation reaction of aromatic aldehydes, 2-aminobenzothiazole, and β-naphthol to afford corresponding 1-((benzo[d]thiazol-2-ylamino)(aryl)-methyl)naphthalen-2-ol derivatives. The inexpensive and non-toxic ionic liquids can be reused several times without noticeable loss of their activities.
