Abstract

Our interest in the Favorskii rearrangement of dichlorinated methyl ketones3v4 and the reactions of chlorinated 1, 3-cyclohexanedione monomethyl enol ethers with sodium methoxide5 prompted us to explore the reactivity of dichlorinated aliphatic P-diketone monomethyl enol ethers. As model compounds the monomethyl enol ethers of 1, l-dichloro- 2, 4-pentanedione (l), prepared by condensation of methyl dichloroacetate and acetone in ...
