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.

4-[(4-hydroxy-1-naphthyl)phenylmethylen]-1(4H)-naphthalinone - The indicator substance from 'α-naphtholbenzein', part 1: Benzeines

The red brown mixture of E/Z-isomeres 3/6 were isolated from 'α-naphtholbenzein', a mixture of various substances. Compounds 3 and 6 are the real indicator substances in 'α-naphtholbenzein', which is used to indicate titrations of weak bases and acids. The reduction of 3/6 give only the colorless 9. Its 4,4'-connections are proved by 1H-NMR-spectroscopy after OH-methylation.
