Abstract: NEW PHTHALIMIDINE COMPOUNDS ARE DESCRIBED WHICH ARE PRODUCED BY REACTING A SCHIFF BASE WITH CARBON MONOXIDE AT 150*C.-300*C. IN THE PRESENCE OF A CATALYTIC AMOUNT OF COBALT CARBONYL IN ACCORDANCE WITH EQUATION:

1-(R''-N=C(-R)-),4-((4-(R''-N=C(-R)-)PHENYL)-A-)BENZENE

--CO-> 1-(O=),2-R'',3-R;6-((1-(O=),2-R'',3-R-ISOINDOL-6-YL)

-A-)ISOINDOLINE

THESE NEW COMPOUNDS PROVIDE A MORE ECONOMIC ROUTE IN THE PRODUCTION OF AROMATIC TETRACARBOXYLIC ACIDS.
