Beschreibung
Zusammenfassung:	(3-oxoisoindolin-1-ylidene)propandinitrile derivatives of formula (I) are new, where Y1, Y2, Y3 = H or halogen; X1 = H, halogen, -OR1, -NHR1, -COOR1, -COR1, -NO2 or -NR1R2; R1, R2 = H, 1-20C aliphatic, 5-20C cycloaliphatic or 6-20C aromatic (all optionally substituted); X2 = halogen, -OR1, -NHR1, -COOR1, -COR1, -NO2, -NR1R2 or (II)-(V); Y4-Y7 = H or halogen; A1, A2 = OR5, H, F, Cl, Br or I; R5 = H or (optionally halogenated) alkyl; and R3, R4 = as X1. La présente invention propose des dérivés de (3-oxoisoindoline-1-ylidine) propanedinitrile de formule 1 : (CF DESSIN DANS BOPI) ainsi que leur procédé de préparation, ces dérivés étant utiles en tant que chromophores optiquement actifs.
