Abstract (en)
[origin: WO03095401A1] The invention relates to a method for the production of substituted trifluoroethylenes, wherein a compound of formula (II), wherein R represents optionally carboxy, halogen, C1-C6-alkoxy, C1-C6-alkoxycarbonyl or C1-C4-alkylcarbonyloxy substituted C1-C6-Alkyl, or a group (III) wherein R' and R'', independently from each other, represent hydrogen or C1-C6-alkyl, or both, together with the nitrogen atom to which they are bonded, jointly represent cycloalkyl with 3-5 carbon atoms, wherein optionally one ring member is replaced with oxygen or sulphur and which is optionally substituted one to four times by C1-C4-alkyl, trifluoromethyl or C1-C4-alkoxy, and Hal represents chlorine, bromium or iodine, preferably chlorine or bromide, are brought into contact in a polar medium, containing water, with a dehalogenating agent.
