Aluminum triisopropoxide is a chemical compound of aluminum from the group of alcoholates .
Extraction and presentation
Aluminum triisopropoxide can be produced by reacting amalgamated aluminum with isopropyl alcohol (similar to the process with tert-butyl alcohol ).
properties
Aluminum triisopropoxide is a flammable, moisture-sensitive white solid with an alcoholic odor that decomposes in water. Aluminum triisopropoxide is hydrolyzed to aluminum oxide by moisture . It is a versatile oligomeric Lewis acid catalyst.
The compound has a tetrameric structure.
use
It is used as a specific reducing agent in the Meerwein-Ponndorf-Verley reduction or in a catalytic amount in the Oppenauer oxidation .
