Copper-catalyzed C–N cross-coupling reactions for the preparation of aryl diamines applying mild conditions
摘要:
In this work, aryl diamines were prepared by C-N cross-coupling reactions between aryl halides and ethylenediamine. These reactions were successfully catalyzed by low quantities of Cu2O or CuO (1 mol %) employing low reflux temperature and low diamine excess. Products were afforded in good yields (up to 95%).

The thermodynamics of binding between native α- and β-cyclodextrin towards several p-nitro-aniline derivatives was examined, in order to gain further insights about the occurrence of different interaction modes for the two hosts. Valuable information was achieved regarding the ‘expanded hydrophobic sphere’ of α-cyclodextrin. Furthermore, very interesting and unexpected aspects of the behavior of β-cyclodextrin
