✦ Synopsis

Acylation of halogen-contahfing electron-rich aromatic and beteroaromatic compounds with 15-ethylsulfanylpropionyl tetrafluorobomte leads to the formation of 6membered sulfonium salts fused with aromatic or heteroaromatic rings. Base induced cleavage of sulfonium salts gave ethylsulfanyl substituted aryl vinyl ketones. Cyclic sulfonium salts can also be converted into corresponding thiopyran-4-ones by treatment with thiourea in MeOH.
