2. Synthesis Method
The compound is likely synthesized via cross-coupling reactions, such as the Suzuki-Miyaura coupling. This would involve reacting a propyl-substituted aryl halide with a 2.3-difluoroethoxy-substituted arylboronic acid/ester in the presence of a palladium catalyst, a base, and a ligand. The synthesis may also involve steps to construct the bicyclohexyl ring system. Optimal conditions depend on substrate reactivity and catalyst selection.
3. Applications
- Liquid Crystals: The rigid biphenyl backbone and alkyl/bicyclohexyl substituents suggest potential use in liquid crystal materials, where such structures influence molecular alignment and optical properties.
- Organic Synthesis Intermediate: Could serve as a precursor for more complex molecules due to its bifunctional structure.
4. Safety Information
- Handling: Follow standard chemical safety protocols (e.g., use gloves, goggles, and fume hoods).
- Storage: Keep in a cool, dry place, away from oxidants and strong acids.
- Disposal: Consult local regulations for hazardous waste disposal.
- Customs Code: Likely similar to related biphenyl compounds (e.g., 2902909090).
