Boron-based mixed anhydrides are rapidly reactive, easy to prepare, cheap, efficient, and general acylating reagents capable of selectivity when chelation is possible. High yields of various esters, amides and thioesters are quickly obtainable and the products are easy to isolate in high purity. The method is readily used under multiple parallel synthesis conditions and is readily scaleable.
