Ferricchloridehexahydrate is a highly efficient catalyst for the regioselectivearylation of α-amidosulfones. The products undergo further Friedel-Craftsalkylations with heteroaromatic or electron-richarenes to afford unsymmetrical or bis-symmetricaltriarylmethanes.

his 75th birthday. Abstract Niobium pentachloride is an efficient and useful Lewis acid to conduct Friedel–Crafts hydroxyalkylation between arenes and (hetero)aromatic aldehydes, to generate triarylmethanes. This practical methodology offers several advantages, such as short reaction time, mild experimental conditions, and excellent yields. Niobium pentachloride is an efficient and useful Lewis acid
