Physicochemical Study on Leuco Triarylmethane Dyes; Unusual Carbon-Carbon Bond Cleavage Involving an Elimination of Dimethylaniline

Upon heating of the leuco triarylmethane dyes (2a) and (2b) with excess phosphoryl chloride under reflux, these compounds underwent a normal chlorination followed by a de-anilination process to give (3a) and (3b),respectively.Replacement of the p-dimethyl
