General description

Bis[(pinacolato)boryl]methane is an aryl boronate ester.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for catalytic efficiency. Click here for more information.

Application

Bis-boronate has been reported by Morken and coworkers to be a key building block in the synthesis of enantioenriched secondary boronate esters, which undergo facile Suzuki-Miyaura coupling with minimal erosion of enantiopurity.
Bis[(pinacolato)boryl]methane may be used in the preparation of trans-vinyl boronate esters, via the Boron-Wittig reaction.
