The insertion of 1,1-diphenylethylene into the Mg-Mg bond of two magnesium(I) dimers, [(ArNacnac)Mg-]2 (Ar = C6H2Me3-2,4,6 (Mes); C6H3Et2-2,6 (Dep)), yielding 1,2-dimagnesioethane products, [{(ArNacnac)Mg}2(μ-CH2CPh2)], is described. These reactions are readily reversible at room temperature and thus represent the first examples of room-temperature reversible redox processes for s-block metal complexes. The 1,2-dimagnesioethane products are highly activated magnesium alkyls and show unprecedented, uncatalyzed reactivity toward H2, CO, and ethylene. Computational studies have investigated the mechanisms of all presented reaction types.

C=C 键可逆插入镁 (I) 二聚体：生成高活性 1,2-二氧化镁乙烷化合物

1,1-二苯基乙烯插入到两个镁（I）二聚体的 Mg-Mg 键中，[(ArNacnac)Mg-]2 (Ar = C6H2Me3-2,4,6 (Mes); C6H3Et2-2,6 ( Dep))，描述了产生 1,2-二氧化镁乙烷产品 [{(ArNacnac)Mg}2(μ-CH2CPh2)]。这些反应在室温下很容易可逆，因此代表了 s 区金属配合物的室温可逆氧化还原过程的第一个例子。1,2-二氧化镁乙烷产品是高度活化的烷基镁，对 H2、CO 和乙烯表现出前所未有的未催化反应性。计算研究已经调查了所有呈现的反应类型的机制。
