Descripción general

Mercury(II) bromide (HgBr2) affords 1:1 adducts on reaction withN,N,N′,N′- tetramethyl-o-phenylenediamine. Single-crystal X-ray diffraction studies of these adducts have been reported. It forms complexes by reacting with 3,12-dimethylbenzo[a]quinoxalino[2,3-c]phenazine ligand.Mercury(II) bromide (HgBr2) may be used in the preparation of mononuclear [Hg(L1)Br2] and 1D polymer [Hg2(L2)Br4]n[L1 = (N,N-diethyl,N′-(pyridin-2-yl)formylidene)ethane-1,2-diamine and L2 = (N,N-diethyl,N′-(pyridin-2-yl)benzylidene)ethane-1,2-diamine]. It may also be used as a promoter in the glycoslyation reaction of alcohols.

Application：

Mercury(II) bromide is used as a reagent in the Koenigs-Knorr reaction, which forms glycoside linkages on carbohydrates. It is also used to test for the presence of arsenic, as recommended by the Pharmacopoeia.
