Abstract: 3-(4-Phenyl-1,3-dithiolan-2-ylidene)pentane-2,4-dione (2) was prepared in moderate(47%) yield by the reaction of acetylacetone with carbon disulfide and 1-(1,2-dibromoethyl)benzene using potassium carbonate as base.Under the optimized conditions, the condensation of compound 2 with arylaldehydes led to the corresponding products α-acetyl-α′cinnamoyl ketene dithioacetals 1d and α,α′-dicinnamoyl ketene dithioacetals 1e, respectively, in high to excellent yields.
