Abstract
Acylation of halogen-containing electron-rich aromatic and heteroaroma tic compounds with beta-ethylsulfanylpropionyl tetrafluoroborate leads to the formation of 6-membered sulfonium salts fused with aromatic or heteroaromatic rings. Base induced cleavage of sulfonium salts gave e thylsulfanyl substituted aryl vinyl ketones. Cyclic sulfonium salts ca n also be converted into corresponding thiopyran-4-ones by treatment w ith thiourea in MeOH. (C) 1998 Elsevier Science Ltd. All rights reserv ed.
