For the first time, the tetrahedran structure substituted at the tops with tert-butyl was obtained in 1978 by Gunther Meyer [1] . The unsubstituted tetrahedran was never synthesized. This is due to the fact that the angle between the carbon atoms in it is only 60 °, which is much less than the optimal 109.5 °. This creates a lot of tension in the molecule and it turns out to be extremely unstable. In the synthesized derivatives of tetrahedran, the substituents at the vertices create a kind of “corset” that restrains the structure.
