| Hazard Information | Back Directory | [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. | [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. |
