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.

(Chemical Equation Presented) Reactions of arenes and heteroarenes with aromatic aldehydes proceeded smoothly in the presence of a catalytic combination of [Ir(COD)Cl]2-SnCl4 to afford the corresponding triarylmethane derivatives (TRAMs) in high yields. This 100% TRAM selective transformation is clean and eliminates the use of acid systems.

An economical way to obtain new monomers, precursors of electron transfer polymers, is described. These monomers were obtained by a Heck reaction between amino or halogeno-2,5-dimethoxydiarylmethane and methylacrylate. Different routes for the ionic reduction of various acetophenones to the corresponding diarylmethanes were studied. The yields and the nature of the by-products was stongly dependent upon the reaction conditions.
