    Abstract: Basic dyes of formula (I): (where R is H, 1-4C alkyl, 2-3C hydroxyalkyl, cyanethyl, 2-5C carbalkoxyalkyl, methoxyethyl, ethoxyethyl, 4-11C alkanoyloxyalkyl, benzyl, phenylethyl, phenyl opt. substd. by methyl, methoxy or ethoxy, or the gp. R1 is 1-4C alkyl, 2-3C hydroxyalkyl, cyanethyl, methoxyethyl, ethoxyethyl or phenyl, R2 is as R; R3 is as R1; X, Y are each H, Cl, methyl, methoxy or ethoxy; A is phenyl opt. mono- or disubstd. by Cl, OH, methyl, methoxy, ethoxy or sulphonic acid gp. or a gp. of formulae: in which R4 is H, Cl, methyl, methoxy or ethoxy; R5 is H or Cl; X- is an anion) are obtained by dehydrogenating cpds. of formula (II): with benzoquinones substd. by F, Cl, Br or Cn or nitro-substd. phenanthrene -quinones in the presence of O2 and catalysts contg. complex heavy metals (where A' is as A or a gp. of formula.
