| | Triflic Anhydride Usage And Synthesis |
| Description | Triflic Anhydride is the acid anhydride derived from triflic acid. It is a strong electrophile, useful for introducing the triflyl group, CF3SO2.
| | Uses |
Triflic anhydride is commonly used in organic chemistry to convert oxygen-containing compounds to triflates and for the electrophilic activation and subsequent conversion of amides, sulfoxides, and phosphorus oxides.
| | Preparation | Triflic anhydride is prepared by dehydration of triflic acid using P4O10.
| | Health Hazard |
Triflic anhydride is readily hydrolyzes to the strong acid triflic acid, it is very harmful to skin and eyes.
