Aliphatic and aromaticcarboxylicacids are rapidly converted into potassium acyltrifluoroborates (KATs) by copper-catalyzed borylation of their mixed anhydrides. This scalable method is compatible with a broad range of functional groups and allows for the facile preparation of aliphatic and aromatic KATs, including KATs derived from Fmoc- and Boc-protected amino acids.
