The condensations of 3,4:9,10-perylenetetracarboxylic dianhydride with alkylamines (isobutyl-, pentyl-, hexyl-, and octylamines) were spectroscopically determined.Under all of the reaction conditions employed, N-alkyl-3,4:9,10-perylenetetracarboxylic monoanhydride monoimide (2a-d) (alkyl=a; isobutyl, b; pentyl, c; hexyl, d; octyl) were obtained.As the reaction proceeded, the yield of 2a-d increased at an initial stage but decreased gradually after reaching a maximum.This maximum yield of 2a-d was: 2a; 85-88percent, 2b; 85-89percent, 2c; 78-84percent, 2d; 79-85percent.The kinetics of the reaction were also examined.
