DERIVATIVES OF IRON PHTHALOCYANINE AS CATALYST OF OXIDATION OF TRIARYLMETHANE DYE LEUCOCOMPOUNDS AND A METHOD OF SYNTHESIS OF TRIARYLMETHANE DYES

摘要

FIELD: organic chemistry. SUBSTANCE: synthesis of triarylmethane dyes is carried out by catalytic oxidation of corresponding leucobases with hydrogen peroxide in the presence of newly synthesized substituted derivatives of iron phthalocyanine iron tetrakis-4-[bis-(2-hydroxyethyl)-sulfamoyl] -phthalocyanine or iron tetrakis-4-(dibutylsulfamoyl)-phthalocyanine, or iron tetra-4-(phenylsulfonyl)-phthalocyanine, or iron tris-4-[(2-hydroxyethyl)sulfamoyl] -phthalocyanine, or iron tetra-3-nitrotetra-5-(tert. -butyl)-phthalocyanine, or iron tetra-3,3^II, ,6,6^II,-hexoxyphthalocyanine, or iron tetra-3,3^II, 6,6^II,-hexoxy-di-4^I, 4^III-(tert. -butyl)-phthalocyanine. EFFECT: improved method of synthesis. 3 cl, 1 tbl
