Process to manufacture polycyclic compounds

In the preparation of polycyclic N-heterocyclic compounds of formula (I) by reacting aromatic di- or tetracarboxylic acids of formula A(COOH)2 (II) or their anhydrides and/or esters with aromatic diamines of formula B(NH2)2 (III), reaction is carried out in a medium containing water and a hydrotropi...

Zusammenfassung:	In the preparation of polycyclic N-heterocyclic compounds of formula (I) by reacting aromatic di- or tetracarboxylic acids of formula A(COOH)2 (II) or their anhydrides and/or esters with aromatic diamines of formula B(NH2)2 (III), reaction is carried out in a medium containing water and a hydrotropic compound with a relative dielectric constant epsilon of 20-60 (at 25 degrees C); in which A, B = ortho-phenylene, ortho-naphthylene, peri-(1,8)-naphthylene or arylene of more than 2 condensed benzene rings, which are bridged in the ortho-position or corresponding to a peri-position in naphthalene, and may be substituted. Also claimed are plastics containing dye(s) prepared by this method.
