چکیده
|
A so_3 h-containing solid acid namely so3h-functionalized phthalimide (sfp) was synthesized from phthalimide and chlorosulfonic acid, and identified by studying its ft-ir, 1h and 13c nmr, mass, xrd, tg and dtg spectra. afterward, its catalytic activity was examined for the solvent-free condensation of dimedone (5,5-dimethyl-1,3-cyclohexanedione) (2 eq.) with arylaldehydes (1 eq.). the results showed that sfp is a highly efficient catalyst to promote the title reaction for the preparation of 9-aryl-1,8-dioxo-octahydroxanthenes.
