Abstract: A facile approach to the synthesis of the title compounds 3 are reported in this paper.Assisted by potassium ethylthioate,2-acetyl-2-aroyl ketene dithioacetals 2(prepared easily from aroylacetones 1)were deacetylated to afford the title compounds 3.The reaction conditions from 1 to 3 were very mild and the yields were high.

Key words: α-Aroyl ketene dithioacetals, Synthesis, Potassium ethylthioate, Deacetylation
