Photolysis of cyclic 1,2,3-butatriene 1 exclusively affords cyclopropane 2 for which an unprecedented initial isomerization to a methylenecyclopropanylidene is proposed. Thermolysis of 1 produces butadiene 3 in 83% yield. Formation of 3 is an apparent disallowed S, A [2+2] cycloaddition but we will argue that it is actually an allowed [4+2] cycloaddition.
