Synthesis and Complexes of Fluoroalkoxy Carbenes

Gripping ligands: A series of fluoroalkoxy‐functionalized imidazol‐2‐ylidene ligands were synthesized by the alkylation of a range of commercially available azoles with hexafluoroisobutylene oxide. The deprotonation of these species with a strong base cleanly generated the free carbenes, which acted...

Zusammenfassung:Gripping ligands: A series of fluoroalkoxy‐functionalized imidazol‐2‐ylidene ligands were synthesized by the alkylation of a range of commercially available azoles with hexafluoroisobutylene oxide. The deprotonation of these species with a strong base cleanly generated the free carbenes, which acted as tridentate chelating ligands (see scheme).
