Zusammenfassung:1,2,3,5,6,7-Hexahydrobenzo(1,2-c:4,5-c')dipyrrole, also called 'di- isoindoline', has been synthesized and characterized both spectroscopically and by means of suitable derivatives. It is a potential starting material for numerous syntheses and is suitable for copolymerization to form new copolymers. Evidence of the potential of 'di-isoindoline' as a monomer for producing high thermal capacity polysulfones and polyamides is obtained from the observed high melting points of the ditosyl and diacetyl derivatives.
