ABDOLMOHAMMADI, Shahrzad; AFSHARPOUR, Maryam  and  KESHAVARZ-FATIDEH, Shima. An efficient green synthesis of 3-Amino-1H-chromenes catalyzed by ZnO Nanoparticles thin-film. S.Afr.j.chem. (Online) [online]. 2014, vol.67. ISSN 1996-840X.

A very simple and environmentally benign approach for the synthesis of 3-amino-1ff-chromenes is described using ZnO nanoparticles thin-film as an efficient heterogeneous catalyst in green media, namely water. The mild reaction conditions, reusability of the catalyst, easy work-up and high yields of products make the present protocol sustainable and advantageous compared to conventional methods.

Keywords : 3-Amino-1H-chromene; aqueous medium; hydrothermal solution method; reusability of the catalyst; ZnO nanoparticles thin-film.
