Full TextAbstract
A new copper acetylacetonate immobilized on halloysite nanotube (HNT) was synthesized. For this purpose, (3-aminopropyl)trimethoxysilane (AMPTSi) was covalently bonded to the surface of halloysite nanotubes, and then copper acetylacetonate was immobilized onto the modified support. The chemical and physical structure of Cu(acac)2/AMPTSi/HNTs were characterized via various analyses such as TEM, SEM, EDS, FTIR, XRD, TGA, and N2 adsorption–desorption. The efficiency of this catalyst was studied in a one-pot three-component reaction of benzaldehydes, dimedone, and malononitrile/ethyl cyanoacetate for the synthesis of 4H-chromenes. For all substrates, good to excellent yields of the corresponding 4H-chromenes were obtained.
