Abstract
Short-lived manganese(V) was generated by reduction of the permanganat e ion with As(III) in acidic solution. It is unstable against dispropo rtionation, but this can be suppressed by oxidizable substrates such a s alcohols, formic acid, phosphorous acid and Mn(II),reacting rapidly with transient Mn(V). The relative reactivities of Mn(V) toward variou s substrates and manganese(II) were characterized by competition exper iments. The possible mechanisms of these fast reactions are discussed.
