Description and Uses
Triethyloxonium tetrafluoroborate 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.
