Bromothiophene Reactions. I. Friedel-Crafts Acylation
Friedel-Crafts acylation of 2,5-dibromo- and 2,3,5-tribromothiophenes with different acyl chlorides and anhydrous aluminium trichloride has been studied.The reaction afforded a mixture of acyl derivatives and tetrabromothiophene.The results obtained suggest a mechanism which involves the formation of bromine cations in the reaction medium.Several products obtained in this reaction are described.
