The anion of this compound attacks a trialkylboron compound to produce boric acid and an anti-Markonikov alcohol in Brown hydroboration-oxidation. Alkyl derivatives of this compound also promote anti-Markonikov addition of hydrobromic acid to alkenes because its weak single bond is a radical initiator. Iron and this compound oxidize wastewater in Fenton's reagent. It spontaneously disproportionates because its central atom's oxidation state is -1.
