Descripción

Descripción general

Diisobutylaluminum hydride is commonly used as a reducing agent in organic synthesis.

Aplicación

Diisobutylaluminum hydride can be used in the following protocols:

• As a promotor of Tishchenko reaction of aldehydes.
• Conversion of benzylidene acetals of 1,2-and 1,3-glycols to the corresponding monobenzyl ethers of the glycols.
• To generate a novel chiral reducing agent based on (S)-proline for the asymmetric reduction of prochiral ketones.

Envase

Supplied in a Sure/Pac^™ cylinder and has a 1/4-turn bronze ball valve with a female 1/4" NPT outlet thread (Z122661) installed. Before using the cylinder, ensure that the valve is closed, then remove carbon steel plug that seals the outlet valve.
