Trapping a Difluorocarbene-Platinum Fragment by Base Coordination

Trapping a Difluorocarbene-Platinum Fragment by Base Coordination

Caught in the act: Evidence for the intermediacy of difluorocarbene–platinum species along the acidic degradation of PtCF3 bonds was gained by trapping a base‐stabilized PtCF2 moiety (see scheme). Attack of an N nucleophile (py*) to the highly electrophilic and extremely reactive difluorocarbene c...

Zusammenfassung:Caught in the act: Evidence for the intermediacy of difluorocarbene–platinum species along the acidic degradation of PtCF3 bonds was gained by trapping a base‐stabilized PtCF2 moiety (see scheme). Attack of an N nucleophile (py*) to the highly electrophilic and extremely reactive difluorocarbene carbon atom takes place with CN bond formation.
