of terminal acetylenicketones with NaI or LiBr gave almost exclusively E-β-iodo- or E-β-bromovinyl ketones in trifluoroacetic acid, while Z-β-iodo- or Z-β-bromovinyl ketones were the major products in acetic acid. Trimethylsilyl iodide and bromide reacted smoothly with acetylenicketones at −78°C to give TMS-allenolates which were readily converted to β-iodo- and β-bromovinyl ketones, respectively
