Description

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.
