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.
General description
Potassium 3-furoyltrifluoroborate belongs to the class of compounds known as potassium acyltrifluroborates (KATs). This heteraroyl trifluoroborate salt is stable and does not readily undergo trimerization.
