Ion‐molecule reactions of (acac) 2 M + ions (M = Fe, Co) with macrocyclic thiourea derivatives (L) were studied. The formation of acacML + and acacM(L – H) + were observed. AcacM(L – H) + ions arise from loss of the hydrogen atom of the NH group. The ion peak intensity ratios, Z = [acacML + ]/[acacM(L – H) + ], for M = Co are higher than those for M = Fe, in accordance with the easier reduction of Co(III) to Co(II) than that of Fe(III) to Fe(II). It is proposed that the metal‐containing ions preferentially attack the thiourea fragment of the macro‐cycles studied.
