Infobox references

Tetra-tert-butylethylene is a hypothetical organic compound, an hydrocarbon with formula C₁₈H₃₆, or ((H₃C-)₃C-)₂C=C(-C(-CH₃)₃)₂. As the name indicates, its molecular structure can be viewed as an ethylene molecule H₂C=CH₂ with the four hydrogens replaced by tert-butyl -C(-CH₃)₃ groups.

As of 2006, this compound had not yet been synthesized, in spite of many efforts. It is of interest in chemical research as an alkene whose double bond is strained but protected by steric hindrance. Theoretical studies indicate that the molecule should be stable, with a strain energy of about 93 kcal/mol.
