Abstract
10% mol SmI3 catalysed the Friedel–Crafts acylation of aromatic ethers by acyl chlorides in acetonitrile with the yields of 48–82%. Reactions of various substituted aromatic ethers with acyl chloride were studied. The structures of compounds were established by IR and 1H NMR. The main product obtained with anisole is the para-substituted compound with only a trace (<5 %) of meta and ortho substituted products. This shows that the acylation of aromatic ethers is highly regioselective in the presence of SmI3, a pattern repeated with the other aromatic ethers used.
