Sodium, magnesium, ferric, zirconium and aluminum hydrogen sulfates have been used as efficient reagents in organic chemistry. A broad range of reactions including deprotection, oxidation, C-C, C-N and C-O bond formation and cleavage took place in the presence of these reagents under mild and completely heterogeneous reaction conditions in good to high yields. In many cases the reagents were recycled and reused.
