Physical Properties
Physical Form
Colorless to pale yellow liquid.
Triethylborane is very soluble in hydrocarbons, ethers and chlorinated hydrocarbons.
Reagent for reduction of beta–hydroxy-ketones to syn-diols. As a radical source and as a radical initiator.
Analysis Method
Purity for neat material based upon IR. Concentration of THF solution based upon boron titration.
Storage & Shipping
Shelf Life
Four years in unopened, original packaging. Based upon like compounds.
Storage / Stability
Neat triethylborane is a spontaneously combustible liquid, burning with a green flame. Solutions of TEB; <18 wt% hexane or <14 wt% in THF are non-pyrophoric. Small exposure to air will oxidize TEB solutions to borinic esters and other borate materials. TEB does not react readily with atmospheric moisture or water in the solution.
