Abstract: | The dissolution kinetics of M* anodes (M* = Al, Cd, Sn, Sb, Bi) during electrolysis of molten complexes MAl2Et6 ] (M = Na, K, Rb, Et4N; = F, Cl) is studied. Parallel dissolution paths are discovered: through a limiting discharge of electrolyte components and through a limiting electrooxidation of adatoms and clusters of M* present at the electrode surface. Substantiated is a mechanism of electrosynthesis of ethyl derivatives M*Et
