A facile and efficient microwave-assisted reaction of 1,8-naphthalicanhydride derivatives with primary amines, leading to the synthesis of 1,8-naphthalimides, has been developed. Subsequently, the free radical scavenging properties of the 1,8-naphthalimide derivatives were evaluated against 2,2-diphenyl-1-picrylhydrazyl (DPPH•). The results showed that the scavenging activities of compounds 2a, NBNA

AbstractEfficient synthesis of fluorescent probes based on 1,8-naphthalicanhydride from acenaphthene with the help of microwave irradiation is described. Application of microwave dielectric heating helped improve the yield of the products (>85%) and also reduced the formation of undesired side-products. Graphical Abstract
