Abstract: New methods have been developed for the synthesis of the third representative of
the homologous series of diamond-like hydrocarbons, triamantane, with a yield of up to 78%,
by skeletal isomerization of iso-compositional endo-endo- and exo-exo-heptacyclo
[9.6.1.02,10.03,8.04,6.05,9.012,17]octadecanes under the action of aluminate ionic liquids. For the
first time, the synthesis and transformation of new C18H26 hydrocarbons - endo-exo- and exo-exo-hexacyclo[8.6.1.15,8.02,9.03,7.011,16]octadecanes into triamantane was carried out. It has
been established that for the successful conversion of polycyclic hydrocarbons of the composition
С18H26 containing two more hydrogen atoms in the molecule than in triamantane, the
addition of Pd/C to the ionic liquid is necessary.
