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.
