| 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. |
