| | 1,2-Difluorobenzene Usage And Synthesis |
| Chemical Properties | colourless liquid | | Uses | 1,2-Difluorobenzene is used in electrochemical analysis of transition metal complexes. 1,2-difluorobenzene is also a potent inhibitor of NMDA receptor. | | Uses | 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 is used as solvent in electrochemical studies on transition metal complexes. It is also applied as a solvent useful for electrochemical studies on transition metal complexes. | | Definition | ChEBI: A difluorobenzene carrying fluoro groups at positions 1 and 2. | | General Description | 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. |
