Acylation of halogen-containing electron-rich aromatic and heteroaromaticcompounds with β-ethylsulfanylpropionyl tetrafluoroborate leads to the formation of 6-membered sulfoniumsalts fused with aromatic or heteroaromatic rings. Base induced cleavage of sulfoniumsalts gave ethylsulfanyl substituted aryl vinyl ketones. Cyclic sulfoniumsalts can also be converted into corresponding thiopyran-4-ones
