Abstract

The environmental friendly reaction of aromatic aldehydes with 5,5- dimethyl-l, 3-cyclohexandione giving 2,2'-arylmethylene bis(3-hydroxy-5, 5-dimethyl-2-cyclohexene-l-one) (3) was carried out in water in the presence of trienthylbenzylammonium chloride (TEBA) . While TsOH existed in the reaction, 3,3, 6,6-tetramethyl-9-aryl-l, 8- dioxooctahydroxanthene (4) or 3,3-dirnethyl-9-(3-hydroxy-5,5-dirnethyl- 2-cyclohexene-l-one-2-yl)-l-oxotetrahydro-xanthene (6) rather than 3 was obtained with excellent yield.

Key words: aromatic aldehyde;CYCLOHEXANEDIONE;TEBA;XANTHENE P;WATER, BENZENESULFONIC ACID P
