Introduction
1. Physicochemical Properties
- Structure: A bicyclohexane framework with a propyl group at the 4-position and an ethyl group at the 4′-position, both in the trans configuration.
Key Characteristics:
The dual alkyl substitutions (propyl and ethyl) contribute to the compound’s hydrophobicity and steric bulk.
The trans configuration enhances structural rigidity, potentially useful in materials requiring defined molecular orientations.
- Analogous Compounds: Similar structures like trans,trans-4-(4-fluorophenyl)-4′-propylbicyclohexyl (CAS: 82832-27-7) provide insights into physicochemical properties, such as melting points (e.g., 71°C) and boiling points (e.g., 388.7±21.0°C).
2. Synthesis Method
The compound is likely synthesized via Williamson reactions or similar nucleophilic substitution reactions. This involves reacting a bicyclohexane precursor with alkyl halides (e.g., propyl iodide and ethyl iodide) in the presence of a strong base. The synthesis may require:
- Purification: Chromatography or recrystallization to isolate the trans,trans isomer.
- Optimized Conditions: Careful control of reaction temperature and stoichiometry to achieve high yields.
3. Applications
- Liquid Crystals: The rigid bicyclohexane structure and dual alkyl substitutions make it a candidate for liquid crystal materials, where it could influence molecular alignment and optical properties.
- Materials Science: Potential use in polymers or coatings due to its bulky structure and hydrophobicity.
- Organic Synthesis: A useful building block for synthesizing more complex molecules with defined steric and electronic properties.
4. Safety Information
- Handling: Follow standard chemical safety protocols (e.g., use gloves, goggles, and fume hoods). Avoid skin contact and inhalation.
- Storage: Keep in a cool, dry place, away from oxidants and strong acids.
- Disposal: Consult local regulations for hazardous waste disposal.
