The diamine Me2NCH2NMe2 (tmmn) is capable of forming simple adducts with most metal(II) ions of the first transition series, but with nickel and cobalt a variety of additional products can be obtained from its reaction with the dihalides. The diamine may be monodentate or bidentate, it may (formally) lose a hydride to generate a cation, and each N–C bond may break, generating new products containing
二胺Me 2 NCH 2 NMe 2 (tmmn)能够与第一过渡系列的大多数
金属(II)离子形成简单的加合物,但对于
镍和
钴,可通过其与二卤化物的反应获得多种附加产物。二胺可能是单齿或二齿的,它可能(形式上)失去
氢化物而生成阳离子,并且每个N–C键可能会断裂,从而生成含有其他
甲基或离子(Me 2 NH 2)+或(Me 2 N CH 2)+。
