Abstract

[reaction: see text] Both DFT and CCSD and CCSD(T) computational methods indicate that 1-fluorocyclopropene can undergo an unprecedented "electrocyclic" automerization process involving a full 180 degrees rotation of its methylene group, without the formation of an intermediate carbene or diradical.
