SYNTHESIS OF SOME DERIVATIVES 9-ARYL-1,8-DIOXOOCTAHYDROXANTHENE AND 2,2’-ARYL-METHYLENE BIS(3-HYDROXY-2-CYCLOHEXENE-1-ONE) IN AQUEOUS MEDIA

This research concerned with the reaction of aryl- benzoylchloride with 1,3-cyclohexanedione in aqueous media (which has been catalyzed by pdodecylbenezenesulfonic acid (dbsa) or sodiumdodecylsulfate (sds)). the product include two types derivatives : seven compounds from 9-aryl-1, 8- dioxooctahydroxanthene derivatives and seven compounds from 2,2’- arylmethylene bis-(3- hydroxy- 2-cyclohexene-1-one) derivatives. the products were diagnosed by the spectral methods (i.r.) and the elements quantities analyses(c.h.n.). add-on products compound's, this method provides several advantages such as good yield, simple work-up procedure and environment friendly
