AN EFFECTIVE ACTIVATION OF ALLYL METHYL ETHERS BY A CATALYTIC AMOUNT OF TRITYL PERCHLORATE IN THE ALLYLATION OF SILYL ENOL ETHERS
In the presence of a catalytic amount of trityl perchlorate, secondary and tertiary allyl methyl ethers smoothly react with silyl enol ethers to afford the corresponding γ,δ-unsaturated carbonyl compounds in good yields.By the combination of this reaction
