설명

일반 설명

1,2-Difluorobenzene undergoes defluorination under very mild conditions by H₂ in the presence of NaOAc over rhodium pyridylphosphine and bipyridyl complexes tethered on a silica-supported palladium catalyst.

애플리케이션

1,2-Difluorobenzene(1,2-DFB) has been used to study the mechanism of dissociation of o-, m- and p-difluorobenzene ions by threshold photoelectron photoion coincidence spectroscopy. It has been used to study the room temperature adsorption of 1,2-DFB, 1,2-dichlorobenzene and 1,2-dibromobenzene on Si(100)2x1 by X-ray photoelectron spectroscopy and temperature programmed desorption. It was used as solvent in electrochemical studies on transition metal complexes.

Solvent useful for electrochemical studies on transition metal complexes.
