The title compound, C14H19BF2O 3, can be described as a resonance hybrid. The entering BF 2 moiety interacts with the C=O (oxo) groups of the parent compound, 5-(ethoxy-carbonyl)adamantan-4-one, generating two conjugated double bonds in the six-membered difluorodioxoborane ring. In spite of the conjugation between the multiple bonds, the tetrahedral configuration of the B atom gives rise to a non-planar conformation of the six-membered ring, which assumes a state intermediate between the boat and sofa forms.
