114: 33: 24: 456: 80: 310:. It was shown that hypercubane lifetime at room temperature tended to infinity. Therefore, it can be assumed that hypercubane is a kinetically stable molecular system. Among the possible hypercubane decomposition products at high temperatures (more than 1000 K) one can observe polycyclic airscrew-like hydrocarbon C 297:
by removing unnecessary hydrogen atoms and adding the ethylene bridges as well as intercarbon bonds between the sp and sp atoms. To facilitate the future hypercubane spectroscopic identification chemical shifts for both C and H NMR-active nuclei have been calculated by Pichierri. Two years later, in
