A new synthesis of aryl vinyl ketones is described. The acylation of active aromatics with the complex of β-ethylsulfanylpropionyl fluoride 1 and boron trifluoride leads to formation of 1-aryl-3-(ethylsulfanyl)propan-1-ones. Subsequent methylation with methyl triflate and elimination with an aqueous solution of KHCO3 results in formation of aryl vinyl ketones in 86-99% yield.
