Overview
Aluminium isopropoxide丨CAS 555-31-7 is an organoaluminium compound widely used as a catalyst and reagent in organic synthesis. It is a colorless or pale yellow solid sensitive to moisture and air. It is a common catalyst in various chemical reactions due to its Lewis acid properties and ability to promote selective transformations.
Applications
1. Catalyst in Organic Synthesis
Meerwein-Ponndorf-Verley (MPV) Reduction:
Aluminium isopropoxide is widely used to reduce aldehydes and ketones to their corresponding alcohols using isopropanol as the hydrogen donor.
Oppenauer Oxidation:
It acts as a catalyst for the oxidation of secondary alcohols to ketones using acetone or other ketones as oxidants.
Asymmetric Synthesis:
Used in chiral catalyst systems for enantioselective reactions in pharmaceutical synthesis.
2. Polymerization Catalyst
Sometimes used as a catalyst in polymerization reactions, especially in the synthesis of polyesters.
3. Precursor for Aluminium Compounds
Serves as a starting material for preparing other aluminium-based catalysts and reagents.
Benefits
✅ Selective Catalysis
Enables mild and selective reduction and oxidation reactions under relatively mild conditions.
✅ Reusable Catalyst
In some cases, aluminium isopropoxide can be recovered and reused, improving process efficiency.
✅ Compatibility
Functions well in various organic solvents, allowing broad application in synthetic chemistry.
✅ Environmentally Friendly
Compared to other metal catalysts, it often provides a greener alternative with fewer side-products.
Summary
Aluminium isopropoxide丨CAS 555-31-7 is an important organometallic catalyst and reagent used primarily in selective reduction and oxidation reactions in organic synthesis. Its role in MPV reductions and Oppenauer oxidations makes it valuable in pharmaceutical and fine chemical industries.
