Hazard Information

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.
