Intramolecular dehydrogenative cyclization involving twofold Csp2-H bond cleavages directed by the amino- or carboxy group proceeds smoothly when using a rhodium-copper catalyst system under air as the terminal oxidant. A variety of fluorene derivatives can be prepared by the environmentally benign procedure.

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.

Doubling up: Two C-H bond activations took place efficiently upon treatment of 1 with a rhodium catalyst to form dehydrogenative cyclization products 2. Furthermore, 3 undergoes similar cyclization and subsequent decarboxylation through the cleavage of two C-H bonds and one C-C bond. Both reactions provide straightforward routes to the fluorene framework. Copyright
