Abstract
AlCl3-ZnCl2/SiO2 as an efficient catalyst for the synthesis of 1,8-dioxo-octahydroxanthene under solvent-free condition
Author(s): Kirti S.Niralwad, Kiran F.Shelke, Bapurao B.Shingate, Murlidhar S.ShingareAmixture ofAlCl3-ZnCl2 supported on silica gel has been found to be a new efficientmediumfor the synthesis of 1,8-dioxo-octahydroxanthene via condensation of aromatic aldehydes and dimedone under solvent-free condition with excellent yields.
