aromatic amines is of continuous interest in chemistry. An exceptionally versatile three‐component reaction that directly transforms inexpensive nitro compounds, boronic acids, and trialkyl phosphites into tertiary aromatic amines has been realized. The reaction tolerates alkyl and aryl substituents on the nitro and boronic acid moieties, as well as functionalized phosphites. No transition‐metal catalysis
Water-soluble monoazo dyes for polyamide fibres wherein the diazo component is 5-aminoiso- thiazole-4-sulphonic acid and the coupling component is an arylamine having no sulphonic acid groups.
