Abstract
Abstract The reaction of Malachite Green (MG, 1a), a model compound of triphenylmethane dye, with ozone proceeded via two paths. The first path involved an ozone attack at the dimethylamino moiety to give a N-formylmethylamino derivative 4a. The second path produced 4-(dimethylamino)benzophenone (2a) and p-(dimethylamino)phenol (6). Other ozonized products, 3a and 5a were also detected. The following is a discussion of the ozonization mechanism.
