General description

Tri-tert-butyl borate is an organoborate commonly used to prepare other borate esters. It is also used as a substrate in Rh-catalyzed carbonylation reactions.

Application

Tri-tert-butyl borate can be used as:

• An additive in the synthesis of chiral α-hydroxy esters by reacting dimethylzinc with α-ketoesters using (−)-2-exo-morpholinoisobornane-10-thiol.
• A starting material in the synthesis of boronate of (+)-pinane-2,3-diol.
