Abstract

The eco-friendly and selective syntheses of 5-methyl-5-aryldipyrromethanes (1–4) in which aryl is FC6H4 1, ClC6H5 2, CH3OC6H5 3 and CH3C6H5 4, have been reported in the presence of citric acid (weak organic acid) and characterised by IR, 1H NMR, 13C NMR and mass spectroscopy. The structures of 2–4 have been confirmed by X-ray crystallography. Anion binding studies of 1–4 with different anions (eg F−, Cl−, CH3COO−, and) have been ...
