- “The transformation of difluorocarbene into 3,3-diflurocyclopropene”

Tetrahedron Lett. 1979, 20, 1913-1916.
The addition of difluorocarbene to benzobarrelene gives the syn and anti 1,2 mono-adducts. Heating of either of them at 200°C in hexadeuteriobenzene generates naphthalene and 3,3-difluorocyclopropene.
