Electrochemical reduction of MnO4−, TcO4− and ReO4− in organic solvents

摘要: Abstract Polarographic and controlled potential coulometric studies on permanganate, pertechnetate perrhenate in organic solvents yield a 1-electron transfer as first reduction step; the half-wave potentials vs S.C.E. obtained solutions of acetonitrile are E 1 2 = −0·60 V , − 1·74 −2·30 respectively. The limiting ionic conductivities MnO4−, TcO4− ReO4− determined. reversibility electrode processes is described terms a.c. efficiencies. Dark green [(CH3)4N]2MnO4, violet [(CH3)4N]2TcO4 olive [(CH3)4N]2ReO4 can be deposited platinum slightly soluble crystalline products by electrolytic acetonitrile.
