Ionic liquid triethylamine-bonded sulfonic acid ([Et3N-SO 3H]Cl, N,N-diethyl-N-sulfoethanammonium chloride) is utilized as a highly efficient, inexpensive and homogeneous catalyst to promote the following one-pot multi-component organic transformations under solvent-free conditions: (i) the condensation of 2-naphthol with arylaldehydes and amides leading to 1-amidoalkyl-2-naphthols, (ii) the reaction of 2- naphthol with aromatic aldehydes and alkyl carbamates to produce 1-carbamatoalkyl-2-naphthols, and (iii) the condensation between 2-naphthol, arylaldehydes and thioamides leading to 1-thioamidoalkyl-2- naphthols. High yields, short reaction times, efficiency, generality, clean process, simple methodology, low cost, easy work-up, ease of preparation of the catalyst, and environmentally benign conditions are some advantages of the protocols.

Caffeine-H3PO4 along with caffeine-HClO4 and caffeine-HNO3 have been prepared and applied for one-pot preparation of bis(indolyl) methanes, 4,4′-(arylmethylene) bis(1H-pyrazol-5-ols), 3,3′-(arylmethylene) bis(4-hydroxycoumarins), 2,4,5-trisubstituted imidazoles, 1‐amidoalkyl‐2‐naphthols, and polyhydroquinolines. The catalysts were characterized using Fourier-transform infrared (FTIR) spectroscopy, 1H and 13C nuclear magnetic resonance (NMR), powder X-ray diffraction (PXRD) analysis, thermogravimetric analysis (TGA), and liquid chromatography (LC)–mass spectroscopy (MS) techniques. The results indicated high product yield, short reaction time, facile separation of catalyst, and easy work-up procedure, suggesting that caffeine-H3PO4 can be considered to be an efficient acidic catalyst for organic transformations.
