Description
1,2-Difluorobenzene, also known as o-difluorobenzene, is a colorless liquid with the chemical formula C6H4F2. It is a difluorobenzene derivative carrying fluoro groups at positions 1 and 2. 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.

Check Digit Verification of cas no
The CAS Registry Mumber 367-11-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,6 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 367-11:
(5*3)+(4*6)+(3*7)+(2*1)+(1*1)=63
63 % 10 = 3
So 367-11-3 is a valid CAS Registry Number.

The gas-phase copyrolysis of chlorotrifluoroethylene with buta-1,3-diene, penta-1,3-diene, or isoprene in a flow reactor at 440–480°C gave 4-chloro-4,5,5-trifluorocyclohex-1-enes. The latter treated with aqueous KOH under condition of phase-transfer catalysis were selectively converted into 1,2-difluorobenzene, 2,3-difluorotoluene, or 3,4-difluorotoluene.
