Dihalogen-2,3-fluor-2-propanals, process for their preparation and their application for obtaining dihalogen-2,3-fluor-2-propionic acid halides and esters, and also alkyl- or arylfluoracrylates. |
摘要 |
<p>New industrial products having the formula (I) and obtention process thereof comprising the halogenation, by direct addition of halogen X2, fluoro-2-acroleine, itself obtained by hydrolisis of acetals from the opening in soft and controllable conditions of alkoxy-1-halogeno-2-fluoro-2-cyclopropanes cycles. Said new products are applied to produce an alkyl or aryl fluoroacrylate comprising the obtention stage of a new intermediary (brominated) product of the series of dihalogeno-2,3-fluoro-2-propanoyls.</p> |
