설명

애플리케이션

Tetrahexylammonium hydrogensulfate can be used as a phase-transfer agent to facilitate certain organic reactions in a two-liquid phase system. For example:

• Epoxidation of α,β-unsaturated ketones in a biphasic dichloromethane/water mixture using sodium perborate.
• Transfer hydrogenolysis of aryl bromides by aqueous sodium formate catalyzed by palladium-triphenylphospine.
• Carbonylation of benzylic and allylic bromides to synthesize carboxylic esters.

기타 정보

Lipophilic phase transfer catalyst. Most efficient catalyst in ruthenium-catalyzed reactions
