Phenol-naphthol-benzeine - Synthesis and chromophoric properties. Part 5: Benzeines

Phenols 4 and 1-naphthol (5) react with benzotrichloride (6) to give benzaurines 7, phenol-naphthol-benzeines 3 and α-naphtholbenzein (1), which were isolated by chromatography. Phenol-naphthol-benzeines 3 are X-/Y-chromophores like α-naphtholbenzeine (1) with two absorption maxima. These are hypsochromically shifted in neutral, in alkaline and in acidic solution, compared with those of 1.
