Abstract

Abstract Poly-(N, N′-dibromo-N-ethyl-benzene-1, 3-disulfonamide)(PBBS) and N, N, N′, N′-tetrabromobenzene-1, 3-disulfonamide (TBBDA) are good activators and catalytic reagents for the acetylation of alcohols, amines, and thiols. The presented method has the advantages of mild conditions, chemoselectivity, and good to high yields, and uses noncorrosive, inexpensive, recyclable, and environmentally friendly catalysts. We have ...
