“…This reaction is particularly sluggish with less reactive perbenzoylated bromides. To advance the classical Koenigs–Knorr glycosylation, many activators including salts of mercury, [5–8] cadmium, [9–11] tin, [12,13] zinc, [14,15] indium, [16,17] silver [18–26] have emerged. [27] Nevertheless, these modifications failed to adequately enhance the reaction that continued to suffer from fair yields, poor reactivity of donors, substrate scope, and the requirement to use excess of toxic or expensive reagents.…”
