The first synthesis of a tetrahedrane stabilized by sterically demanding substituents is described.Tetrahedrane 37 originates from irradiation of tetra-tert-butylcyclopentadienone (26), which can be prepared starting from the already known cyclopentadienone 5.It forms colourless stable crystals.At 135 deg C tetrahedrane 37 valenceisomerizes to the corresponding cyclobutadiene 36.This reaction can be reversed photochemically.
