Clear colorless to brown liqui | [Uses]
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
| [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. |
