Process for the preparation of polycyclic compounds |
| abstract |
Process for the preparation of compounds of the general formula (I) <IMAGE> (I) by reaction of aromatic dicarboxylic acids of the formula (II) <IMAGE> (II) or anhydrides and/or esters thereof with aromatic diamines of the formula (III) <IMAGE> (III) wherein A and B have the meaning given in the description, characterized in that the reaction of (II) with (III) is carried out in a reaction medium which comprises water and a hydrotropic compound which has a dielectric constant epsilon of 20 to 60 at 25 DEG C. |
