General description
2-Bromo-1-ethyl-pyridinium tetrafluoroborate is a coupling reagent employed in the synthesis of amides and esters through amidation and esterification reactions, respectively. It is generally prepared by the reaction of triethyloxonium tetrafluoroborate with 2?bromo pyridine.
Application
Other Notes
Coupling reagent for peptide synthesis; less racemization and faster reaction than with other reagents;e.g. BOP, PyBrOP, PyClU, BTFFH, CMBI
