Rate constants have been determined for the reaction of the tris(2,2′-bipyridyl)iron(II) cation with cyanide ion in mixed aqueous solvents containing up to 30% by volume methanol, ethanol, dioxan, and acetone, and up to 48% by volume t-butyl alcohol. Rate constants have also been determined for this reaction in aqueous solutions containing potassium, tetramethylammonium, and tetra-n-butylammonium halides
已经确定了三(2,2'-联吡啶基)铁(II)阳离子与氰化物离子在混合溶剂中的反应常数,该混合溶剂中甲醇,乙醇,二恶烷和丙酮的体积含量最高为30%,最高为30%。 48%(体积)叔丁醇。在含有钾,四甲基铵和卤化四正丁基铵的水溶液中,也已经确定了该反应的速率常数。根据混合溶剂和盐溶液的既定性能讨论了观察到的反应性趋势。特别地,将反应性趋势与考虑到氰化物离子的估计化学势随溶剂介质组成的变化而预测的趋势进行比较。
