摘要: Condensation of 4-bromo- (4) and 4-nilro-l,8-naphthalimides (5) with 2-aminobenzenethiol gave 4-(2-aminoulicnylthio)-1,8-naphthalimides (7). Cyclisalion 7 by the: Pschorr reaction afforded benzo[k,l] thioxanthene-3,4-dicarboximides (8), also obtained ol amities thioxanthene-3,4-dicarboxylie anhydride (11).
