Article abstract of DOI:10.1016/S0040-4020(01)81530-1

Regiocontrolled synthesis of symmetrical dinuclear products 4 and 8 derived from condensation of 2-naphthalensulfonic acid and formaldehyde was afforded. Acid catalyzed reaction of 4 with formaldehyde gave a mixture of regiocontrolled oligomers with even number of naphthalenic nucleus from which tetranuclear 9 and hexanuclear 10 products were separated. NMR Studies of all these products were carried out, obtaining both the structural characterization and useful informations for the identification of more complex mixtures.
