Abstract
Reactions of the monovalent metal ions Cd+, Co+, Ni+ and Zn+ with electron acceptors in neutral aqueous solution have been studied and three types identified: (a) addition M++ O2→ MO+ 2(M = Ni) M++ olefin →(M—olefin)+(b) oxygen atom transfer M++ N2O → MO++ N2(c) electron transfer M++ S2O2– 8→ M2++ SO– 4+ SO2– 4. In reaction (b) when M= Co, long lived CoIII species are produced. Evidence is also presented for the oxidation of Co2+ by OH (k= 8 × 105 dm3 mol–1 s–1) and by SO– 4(k∼ 2 × 106 dm3 mol–1 s–1) in neutral solution.Keywords
