In this paper, the preparation of 3,3,6,6-tetramethyl-1,8-dioxo-9-aryl-1,2,3,4,5,6,7,8-octahydroxanthene derivatives from aromatic aldehydes and 5,5-dimethyl-1,3-cyclohexanedione in ionic liquid [bmim+][BF4-] is described. Compared with other methods, this new method has the advantages of easier work-up, milder reaction conditions, high yields and environmentally benign procedure. In addition, the fluorescence emission spectra of these compounds are also investigated.
