| Application: | 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-triphenylphospi • Carbonylation of benzylic and allylic bromides to synthesize carboxylic esters. |
| Other Notes: | Lipophilic phase transfer catalyst. Most efficient catalyst in ruthenium-catalyzed reactions |
