설명

애플리케이션

Trimethylboroxine (TMB) is a cyclic anhydride of methyl-boronic acid. It can be been used:

• As a derivatizing agent for gas chromatographic/mass spectrometric analysis.
• In the preparation of methylaluminoxane (MAO) which is used in the polymerization of olefins.
• As an electrolyte additive to enhance the interface stability of electrode/electrolyte.
• In methylation of aryl halides by palladium-catalyzed Suzuki-Miyaura coupling reaction.
• In the preparation of CBS (Corey, Bakshi and Shibata) catalysts for asymmetric reductions of ketones to alcohols.
