Moisture Sensitive
Soluble in methanol. Slightly soluble in chloroform and ethyl acetate.


N-Phenylbis(trifluoromethanesulfonimide) acts as a mild triflating reagent as well as a transparent strong electron-withdrawing p-type dopant in carbon nanotubes. It is also employed as a reactant for the preparation of amphoteric alfa-boryl aldehydes. It plays an important role in the enantioselective synthesis of the core ring skeleton of leucosceptroids A-D and in steroselective sulfoxidation. Further, it is used in the enantioselective synthesis of beta-amino acids through the Mannich reaction. In addition to this, it is used in the preparation of sphingosine 1-phosphate-1 receptor agonists.


Hygroscopic. Store in a cool place. Moisture sensitive. Incompatible with strong oxidizing agents.
