A new method for the meta acylation of anisole and its para-methyl or fluoro derivatives, is described. Addition of two trimethysilyl groups in the 2 and 5 positions (relative to the methoxy group), followed by hydrolysis affords the corresponding 5-trimethylsilyl-3-Cyclohexenones. Electrophilicsubstitution of the silyl group using RCOCl/2AlCl3 at low temperature provides, after final aromatisation
