The rate of the selective oxidation of mercaptoethanol by dioxygen to disulphide, catalysed by Co(II)‐tetrasulphophthalocyanine, is enhanced with a factor 2 à 4 by irradiation with light in the range of 600‐700 nm. This effect can be ascribed to the conversion of dimers of Co(II)‐tetrasulphophthalocyanine to catalytically active monomers.
