连二胺化合物在化学工业、金属螯合剂、多氮杂环和穴状化合物化学中很重要。它们也常用于中间体的合成,以及特殊杂环化合物的合成。仲连二胺通常可用 Na、Mg、AI(Hg)Ti等诱导N取代的亚胺发生二聚反应还原制备。该方法有一些不利因素:较适合仲芳香胺而不适合叔芳香胺或脂肪胺;单分子与双分子还原相互竞争,而单分子还原产品通常是副产物;阴离子中间体形成困难。叔连二胺可在三(二烷基胺基)甲基钒(Ⅳ)或钛度剂存在下,
Even diamine compounds are important in the chemical industry, metal chelators, polyazacycles, and cryptate chemistry. They are also commonly used in the synthesis of intermediates and in the synthesis of specific heterocyclic compounds. Secondary diamine can usually Na, Mg, AI (Hg) Ti induced N-substituted imine occurred dimerization reduction prepared. This method has some disadvantages: it is more suitable for secondary aromatic amines than for tertiary aromatic amines or fatty amines; single molecule and bimolecular reduction compete with each other, while single molecule reduced products are often byproducts; anionic intermediates are difficult to form. Tertiary diamine can be in the presence of tris (dialkylamino) methyl vanadium (IV) or titanium agent,
