Zusammenfassung:Prepn. of N-(ortho-alkylphenyl)-imide cpds. of formula (I), comprises reaction of a cyclic anhydride of formula (II) with an amine of formula (III), with removal of water of reaction at 100-200 degrees C (without addn. of polymerisation inhibitors and without addn. of dipolar aprotic solvents). R =1-6C alkyl; R -R =H, opt. substd. 1-6C alkyl, opt. substd. 2-6C alkenyl, halo, NO2, CN or 1-6C alkoxy; or R +R =R -CH=; or R +R =a covalent bond; R =H or 1-4C alkyl.
