Carbocations and carbenes

Strongly electrophilic carbenes are among the most reactive species in organic chemistry. Some of these species react without an activation barrier with hydrocarbons, nitrogen, or, even, xenon. A number of these species was synthesized and characterized in our laboratory.


Difluorovinylidene forms a strong complex with xenon.


Synthesis of the phenylcation via ionization of matrix-isolated phenyl radicals.

The phenylcation is mentioned in all textbooks of organic chemistry. However, only recently it could be isolated in condensed phase using the matrix isolation technique.
