Uses
Reactant for:
- Preparation of a dialkylborenium ion stabilized by an N-heterocyclic carbene
- Mukaiyama aldol addition
- Preparation of porphyrin dimethyldioxanyl tolyl derivative complex
- Preparation of palladium porphyrin complexes
- Boron-mediated β-alkoxy Me ketone aldol addition reactions
Application
9-Bbn triflate can be used to prepare Lewis acids of vinyloxyboranes and boryl nitrify salts; a catalyst for the coupling of silyl enol ethers and acetals; and a catalyst for the isomerization of epoxides to allyl alcohols.
Preparation
Equimolar amounts of 9-Borabicyclo[3.3.1]nonane and Trifluoromethanesulfonic Acid are mixed in hexane and stirred at 20 °C for 24 h after which time 9-BBN TRIFLATE is isolated by vacuum distillation.
storage
Use in a fume hood; the neat liquid as well as solutions are moisture and air sensitive; therefore the material should be stored and transferred under a dry inert atmosphere.
