Strain energies in [n]triangulanes and spirocyclopropanated cyclobutanes: An experimental study
The enthalpies of formation for trispiro[2.0.0.2.1.1]nonane (3), [3]rotane (4), n-heptyl[3]rotane (6), spiro-[2.3]hexane (7), and the isomeric dispiro[2.0.2.2]octane (8) and dispiro[2.1.2.1]octane (9), as well as [4]rotane (10), have been determined by me
