Triethyloxonium Tetrafluoroborate (CAS: 368-39-8) is used as a powerful alkylating agent, especially for ethylation. It is used for the modification of carboxyl residues in proteins. It is involved in the preparation of μ-amino esters from lactams. It is also alkylating agent for nucleophilic functional groups in organic synthesis.
Triethyloxonium tetrafluoroborate is a powerful ethylating agent, although the hazards are diminished because it is non-volatile. It releases strong acid upon contact with water. When heated to decomposition it emits toxic vapors of boronand Fí. Mutation data reported.
