Tetrahedrane synthesis challenge

A challenge to synthesis this is a consequence of the expected high strain in tetrahedrane. Novel reactions and extraordinary experimental skill are often needed to construct highly strained molecules. 

The synthesis of the parent tetrahedrane must be considered an enormous challenge, in view of the tremendous but thwarted effort expended by the Maier group to this end, but their great success in obtaining several substituted tetrahedranes indicates the quest is by no means hopeless (e.g. Note 4). It is the kinetic stability of tetrahedrane that concerns ns here, for no one would expect it to be the global minimum on the C4H4 potential energy surface. The indication from computational...
