RHA/TiO2-[bip]-NH2+NO3− as an efficient catalyst for the solvent-free synthesis of 1,8-dioxo-decahydroacridine and 2,3-dihydroquinazolin-4(1H)-one derivatives
Abstract
was successfully synthesized and characterized, using of various techniques, including FT-IR, ¹H NMR, ¹³C NMR, TEM, XRD, XPS, TGA, EDX, and SEM mapping. The catalytic performance of this material was then evaluated in the synthesis of 1,8-dioxo-decahydroacridine and 2,3-dihydroquinazolin-4(1H)-one derivatives. The products were formed in very short reaction times under solvent-free conditions with excellent yields. In addition, the reusability of the catalyst was investigated, confirming its stability for at least five consecutive runs and also its ability to use in green and sustainable synthetic processes.
