- A facile iron-catalyzed dual C-C bond cleavage: An approach towards triarylmethanes
-
A facile iron-catalyzed dual C-C bond cleaving reaction involving 1,3-dicarbonyl units along with electron-rich and sterically bulky arenes as efficient carbon-based leaving groups has been developed. The scope of the dual C-C bond breaking reaction was s

- Green synthesis and antiviral activity of novel triarylmethane derivatives via Friedel-Crafts alkylation by polyethylene glycol (PEG-400)
-
A series of novel triarylmethane derivatives (3a-j) were synthesized by a one-pot, two-component method via Friedel-Crafts alkylation of various electron-rich arenes (1a-j) with a wide variety of aldehydes (2a-j) in presence of the polyethylene glycol (PEG-400) as a green solvent at 50-60 °C in good to excellent yields (76-96 %). Their structures were confirmed by FT-IR, 1H NMR, 13C NMR, mass spectrometry and elemental analysis. All the triarylmethanes were tested and evaluated for their antiviral and antifungal activities. Compounds 3b, 3f, 3g and 3i exhibited highest antiviral activities against tobacco mosaic virus (TMV).

- Ruthenium porphyrin catalyzed friedel-crafts type reaction of arenes with imines
-
Cationic ruthenium porphyrin complex was found to be an efficient catalyst for the Friedel-Crafts type reaction of arenes with imines. The use of a structurally rigid tetradentate porphyrin as the equatorial ligand and weakly coordinating axial ligand is the key to bring out the catalytic reactivity of ruthenium for the reaction.
