Physical Properties
Appearance
Appearance Colorless to pale yellow liquid
Solubility
Solubility MDEB is soluble in hydrocarbons and ethers
Application
Preferred reagent for reduction of beta-hydroxy ketones to syn-alcohols. As a reagent to prepare aryl diethylborane compounds for Suzuki coupling.
Analysis Method
MDEB purity calculated by GC. Concentration of THF solution calculated by boron titration
Storage & Shipping
Shelf Life
Four years in unopened, original packaging. Based upon like compounds.
Storage / Stability
Neat methoxydiethylborane is a spontaneously combustible liquid. At concentrations less than 80wt% in THF, the solution is non-pyrophoric. Exposure to air will oxidize MDEB solutions to other borate materials. MDEB also reacts readily with atmospheric moisture upon exposure to air resulting in a decrease in purity.
