| Abstract: | Herein, we demonstrate that tritylamines undergo an unprecedented copper‐mediated cyclization involving the cleavages of two C?H bonds and one C?N bond to give 9‐arylacridine derivatives. This kind of acridines is of interest due to their biological properties and their unique optical and electro‐ and photochemical properties. Some of obtained acridine derivatives exhibit intense fluorescence in the solid state. |
