Boronic acids

Most boronic acids readily undergo dehydration reactions to give a cyclic (trimer) anhydride. Our selection of boronic acids may contain varying amounts of this cyclic anhydride. Fortunately, the acid and the anhydride work equally well in the Suzuki coupling reactions; thus, the two forms are generally regarded as equivalent.
