1,3,5-Tri-tert-butyl-5-(1,3,5-tri-tert-butyl-4-oxo-2,5-cyclohexadienyl)methylbicyclo[4.1.0]hept-3-en-2-one, a Highly Hindered Propane

The title compound, C₃₈H₆₂O₂, is one of the reaction products of diazomethane with two equivalents of 2,4,6-tri-tert-butylphenoxyl. In the crystal structure the cyclopropane ring is almost perpendicular to the basal plane of the boat-configurated cyclohexenone ring.
