“…The products were identified by comparison of their FT-IR, 1 H NMR and 13 C NMR spectroscopic data with those of authentic compounds (prepared by known method) and literature reported data. 13,14,[18][19][20] The polyaniline supported and Clayfen catalysts were prepared using already reported method. 21,22 …”

In these studies, we had observed polyaniline (PANI) supported p-toluene sulfonic acid (TsOH) and FeCl 3 (PANI-TsOH, PANI-FeCl 3 ) as excellent reusable solid acid catalysts for the synthesis of 1, 8-dioxo-octahydroxanthene derivatives 4(a-g) under solvent-free grinding method at mild conditions. Additionally, in the same optimized condition ferric nitrate nonahydrate also acted as (non-reusable) very reactive inexpensive Lewis acid catalyst. The ferric nitrate nonahydrate lost its activity in the form of Clayfen (Clay-supported ferric nitrate) catalyst.

“…A literature survey revealed that the use of SiO 2 -NaHSO 4 for the synthesis of xanthenediones [19], ȕ-enaminones, and 2-methylquinolin-4(1H)-ones [20]. Furthermore, SiO 2 -NaHSO 4 has been used in the protection of aldehydes with 2-mercaptoethanol [18].…”

An easily prepared Fe (III)-derived Lewis acid ionic liquid, [C 4 (mim) 2 ] (FeCl 4 ) 2 , being comprised of dicationic ionic liquid cation and tetrachloroferrate anion, was found to be an efficient, recyclable catalyst for the synthesis of 1, 8-dioxooctahydroxanthenes by one-pot condensation reactions of dimedone/ 1, 3-cyclohexanedione with aromatic aldehydes under mild reaction conditions without utilization of additional organic solvent
