The reaction of terminal acetylenic ketones with NaI or LiBr gave almost exclusively E-B-iodo-or E-8-bromovinyl ketones in trifluoroacetic acid, while Z-Biodo-or Z-B-bromovinyl ketones were the major products in acetic acid. Trimethylsilyl iodide and oromide reacted smoothly with acetylenic ketones
