Triisopropyl Borate
Chemical Formula: C₉H₂₁BO₃
Structure: Borate ester with a boron atom bonded to three isopropoxy groups (-OCH(CH₃)₂). Derived from boric acid and isopropanol.
Physical Properties
- Appearance: Clear, colorless liquid.
- Odor: Mild alcohol-like.
- Reactivity:
- Moisture-sensitive: Hydrolyzes in water, releasing isopropanol.
Applications
- Organic Synthesis:
- Reagent for preparing boronic acids/esters, key intermediates in Suzuki-Miyaura cross-coupling reactions (C-C bond formation).
- Polymer & Materials Chemistry:
- Catalyst/additive in polymers, coatings, and flame retardants.
- Industrial Processes:
- Solvent and stabilizer in chemical manufacturing.
Safety Considerations ⚠️
- Handling:
- Use PPE (gloves, goggles) and work in a dry environment.
- Storage:
- Store in a cool, dry, airtight container away from moisture and incompatible substances.
Summary:
Triisopropyl borate’s boron-mediated reactivity drives its role in organic synthesis and materials science. Its utility in cross-coupling reactions and industrial processes is balanced by strict moisture control and safe handling protocols.
