Li. Simandi et E. Zahonyibudo, RELATIVE REACTIVITIES OF HYDROXY COMPOUNDS WITH SHORT-LIVED MANGANESE(V), Inorganica Chimica Acta, 281(2), 1998, pp. 235-238
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.
