Description
Application
12-Difluorobenzene(12-DFB) has been used to study the mechanism of dissociation ofo-m- andp-difluorobenzene ions by threshold photoelectron photoion coincidence spectroscopy[1]. It has been used to study the room temperature adsorption of 12-DFB 12-dichlorobenzene and 12-dibromobenzene on Si(100)2x1 by X-ray photoelectron spectroscopy and temperature programmed desorption[4]. It was used as solvent in electrochemical studies on transition metal complexes
Purpose
For R&D use onlynot for drug household or other uses.
General Description
12-Difluorobenzene undergoes defluorination under very mild conditions by H2in the presence of NaOAc over rhodium pyridylphosphine and bipyridyl complexes tethered on a silica-supported palladium catalyst
