The selective functionalizations of the fundamental hydrogen-terminated nanodiamonds triamantane 1, as well as the most symmetrical representative of the tetramantanes (C2h-[121]tetramantane 2) were elaborated. Electrophilic reagents (Br2, HNO3) predominantly attack the medial C−H positions of the cages; bromination of 2 gave the medial 2-bromo derivative almost exclusively. Highly selective apical
