General description
1-Bromo-2,4-difluorobenzene undergoes lithiation exclusively at the position having two adjacent halogen substituents, to yield 6-bromo-2,3-difluorobenzoic acid.
Application
1-Bromo-2,4-difluorobenzene has been used in:
- preparation of (2S)-1-(2,4-difluorophenyl)-2-(1,1-dimethyl-1-sila-ethoxy)-propan-1-one
- enantiomeric preparation of the key intermediate of chiral azole antifungal agents by a chemoenzymatic process

Four dibenzofuran-type host materials substituted with a carbazolylcarbazole moiety were synthesized to investigate the effect of substitution position on the material parameters and device performances of host materials. The carbazolylcarbazole moiety was substituted at the 1-, 2-, 3-, and 4-positions
