A molecule on a slippery slope: Lineberger et al. finally managed to observe the oxyallyl diradical 1 using negative ion photoelectron spectroscopy. The singlet state of the oxyallyl diradical is lower in energy than the triplet and corresponds to the transition state for ring closure to cyclopropanone 2.
