Application
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.

[reaction: see text]. An operationally simple and recoverable fluorous CBS methodology was developed. The in situ-generated fluorous oxazaborolidine efficiently catalyzed the reduction of ketones with high enantioselectivity and reactivity. The subsequent recycling of the fluorous prolinol precatalyst was achieved by
