通过2-萘酚与芳基肼的反应一步构筑非对称的1,1'-二芳基-2,2'-二胺化合物（英文）

One-Step Synthesis of Unsymmetric 1,1'-Biaryl-2,2'-diamines by the Reaction of 2-Naphthols with Aryl Hydrazines

报道了一类无金属参与、操作简单的合成方法来制备非对称的1,1'-二芳基-2,2'-二胺化合物.与已知的三步合成法比较,该策略将2-萘酚与芳基肼反应,不需要使用过渡金属催化剂和配体,具有操作简单、一步合成的优点.

A metal-free, operationally simple synthetic protocol for the buildup of unsymmetric 1,1＇-biaryl-2,2＇-diamine compounds was reported. This reaction was performed by the treatment of 2-naphthols with aryl hydrazines under no transition metal catalyst and no ligand conditions, which has the advantages of simple operation and one-step synthesis.
