Abstract:
Data on skeletal rearrangements in the chemistry of cage compounds are reviewed. The main principles of thermodynamically controlled isomerisation of cage hydrocarbons and syntheses of mono- and polycage structures are considered. Data on skeletal reconstruction accompanying functionally substituted carbo- and thia-containing cage-type polycyclanes are systematised. The rules for skeletal interconversions of isomeric tricyclic structures are considered. The bibliography contains 99 references.
