摘要： A green and efficient multicomponent one-pot synthesis of Hantzsch polyhydroquinoline was achieved by the condensation of aldehydes, dimedone, ethylacetoacetate and ammonium acetate at room temperature using environmentally benign modified Montmorillonite supported Ni0-nanoparticles as catalyst. The well dispersed Ni0-nanoparticles having a high surface to volume ratio have promising features for the reaction such as easy removal of the catalyst, solvent-free, shorter reaction time, high product yields (about 95%) and easy work up procedure. There is no significant effect of electron withdrawing or donating nature of substituent on aldehydes in the formation of polyhydroquinoline derivatives. ► Modification of Montmorillonite clay by mineral acid activation. ► In-situ generation of Ni0-nanoparticles on modified Montmorillonite clay. ► Hantzsch polyhydroquinoline synthesis by the supported Ni0-nanoparticle catalyst. ► The synthesis involves no solvent, easy work up and exhibits high yields. 出版者： Elsevier B.V 出版日期： 2012-03 出處： Catalysis communications, 2012-03, Vol.19, p.1-4 資源來源： ScienceDirect (Elsevier) Journals 版權： 2011 Elsevier B.V. 識別號： ISSN: 1566-7367 識別號： EISSN: 1873-3905 識別號： DOI: 10.1016/j.catcom.2011.12.013
