The photolysis of metanilic acid (1) as the sodium metanilate, through quartz under helium at lambda = 254 nm leading to the isomeric anilinesulphonic acids (2 and 3) and aniline (4) has been studied in water. The effects of pH and solvent on products, the acid-base catalysis of the photoreaction (pH-product profile) and the effects of substrate concentration, radical scavenging, triplet sensitization and quenching studies are reported.A mechanism involving a single triplet and a series of sigma-complexes is proposed.
