                                    The equilibrium mixture of 2-phenylamino-5-methoxy-1·4-benzoquinones and semiketals, which depends on the substitution of the components and on the solvent, reacts with o-aminophenols in acetic acid to give triphendioxazines. The synthesis unequivocally proves the structure
