Functionalizations of diamantane, triamantane, and tetramantane with electrophilic reagents (Br2, nitric acid) lead to various apical and medial disubstituted products that were separated and characterized individually. The highly desirable and otherwise inaccessible thermodynamically more stable apical bis-derivatives were obtained with high preparative yields through acid catalyzed isomerizations

Tetraethyl- and tetrabutylammonium permanganate are less prone to explosive decomposition when heated than are benzyl(triethyl)ammonium and methyl-(triphenyl) phosphonium permanganate and are about equally effective as oxidants for the conversion of alkanes into alcohol and ketones.

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

Triamantane was synthesized in 80% yield by skeletal isomerization of a mixture of heptacyclo(8.8.0.02,17.03,11.04,9.012,16.013,18)octadecane and heptacyclo(8.8.0.02,13.03,11.04,9.012,17.014,18)octadecane under the action of the ionic liquid 2AlCl3–Et3N·HCl and mild conditions (50 °С, 8 h). X-ray diffraction analysis confirms the structure of the obtained product.

The C18H24 diamondoid hydrocarbon triamantane reacts with bromine largely at the 2-position and with lead tetrabenzoate largely at the 3-position; 2-bromotriamantane can be isomerised to 9-bromotriamantane and the 9-methyl derivative can be obtained directly from a C19H26 precursor by aluminium chloride-catalysed rearrangement.
