functionalization of fullerenes. This paper describes the facile synthesis of symmetrically (Schemes 1 and 2) and unsymmetrically (Schemes 4 and 5) substituted Tröger base derivatives starting from the corresponding, readily available dihalo compounds. A variety of metal-catalyzed cross-coupling reactions, including Suzukicouplings, palladium-catalyzed cyanation and boronation, and copper-catalyzed amidations

The one-step synthesis of a series of hybrid dibenzo Troger'sbaseanalogues bearing at least one halogen atom is described. The strategy involves a reaction between two different anilines and affords hybrid compounds in yields as high as 46 %, together with the symmetricTroger'sbase products. This straightforward approach requires only one chromatographic step and has the potential to replace multi-step
This study introduces a novel method for producing Tröger's bases by utilizing the rearrangement chemistry of benzyl azide. This method offers a convenient and adaptable pathway for synthesizing these important molecular structures with potential for further advancements. By reacting benzyl azide derivatives with TfOH under the presence of water, this process generates iminium ion, formaldehyde, and
