Application

Hexafluorobenzene can react with:
  • Ethyl magnesium bromide in the presence of transition metal halides to form the corresponding perfluoroarylmagnesium compound that can undergo Grignard reactions.
  • The sodium salt of the appropriate phenol in 1,3-dimethyl-2-imidazolidinone (DMEU) to form the corresponding hexakis(aryloxy)benzenes.

It can be used:
  • As a ligand to synthesize novel ruthenium(0) and osmium(0) hexafluorobenzene complexes.
  • As a solvent and promoter for the ring-closing metathesis (RCM) to form tetrasubstituted olefins in the presence of a ruthenium-based catalyst.
