我们研究了酰基金属化合物，特别是CH_3COMn（CO）s与各种亲核试剂的反应。速率和动力学模式表明，CH3COMn（CO）6的行为很像一个酰胺。此外，CH3COMn（CO）3的酸催化溶剂分解的动力学行为类似于酰胺。我们还研究了CH_3Mn（CO）_3与HCl在甲醇中的反应，以形成甲烷和ClMn（CO）_3。该速率取决于酸浓度，并且通过添加KCl而显著增加。HgCl_2作为裂解剂比HCl好上级，Hg（OAc）_2更好.
We have investigated the reactions of acylmetal compounds, particularly CH3COMn (CO) s, with a variety of nucleophiles. The rates and kinetic patterns show that CH3COMn (CO) 6 behaves much like an amide. Furthermore, the kinetic behavior of the acid-catalyzed solvolysis of CH3COMn (CO) 3 resembles that of an amide. We have also examined the reaction of CH3Mn (CO) s with HC1 in methanol to form methane and ClMn (CO) 3. The rate is dependent on the acid concentration and is significantly increased by additions of KC1. HgClz is superior to HC1 as a cleaving agent and Hg (OAc) 2 is better still.
