| Abstract: | The steric course of bromination of cyclic and acyclic metal enolates in ether, independent of the nature of the metal (lithium or potassium), is identical to that of enols but very different from that of methyl enol ethers. The stereochemical results are compatible with the previously postulated six-centre cyclic halogenation mechanisms of enols |
