Introducing Fe3O4 @SiO2 @KCC-1@MPTMS@CuII catalytic applications for the green one-pot syntheses of 2-aryl(or heteroaryl)-2,3-dihydroquinazolin-4(1 H )-ones and 9-aryl-3,3,6,6-tetramethyl-3,4,5,6,7,9-hexahydro-1 H-xanthene-1,8(2H)-diones

In this study, the new catalytic applications of the dendritic Fe3O4 @SiO2 @KCC-1@MPTMS@CuII meso-porous nanocomposite have been introduced for the green one-pot syntheses of some 2-aryl(or heteroaryl)-2,3-dihydroquinazolin-4(1H)-ones and 9-aryl-3,3,6,6-tetramethyl-3,4,5,6,7,9-hexahydro-1H- xanthene-1,8(2H)-diones. Notably, the presented one-pot procedures offer advantages, such as good -to-excellent yields of the desired products, relatively suitable reaction times, clean and fast work-up, and simple purification procedures. Also, the TONs and TOFs values of the catalyst were calculated and reported. In addition, the mentioned Cu II-containing DFNS-type nanocatalyst could be easily separated from the reaction environment, recovered, and reused at least seven times with a negligible decrease in its catalytic activity and performance.(c) 2022 Elsevier B.V.
