Description General description Potassium (2-phenylacetyl)trifluoroborate (potassium benzyltrifluoroborate, phenylacetyl trifluoroborate) belongs to the class of compounds known as potassium acyltrifluroborates (KATs). This trifluoroborate salt is stable and does not readily undergo trimerization. It undergoes palladium-catalyzed cross-coupling reaction with p-nitro triflate to form the corresponding biaryl. Phenylacetyl trifluoroborate acts as an acyl donor during the amidation of O-benzoyl hydroxylamine to form the corresponding amide. Application Potassium acyltrifluroborates (KATs) are bench, air and moisture stable reagents for rapid chemoselective amide bond formations with hydroxylamines. These amide bond forming reactions proceed under aqueous conditions without the need for coupling reagents or protecting groups. This product was introduced in collaboration with the Bode Research Group.
