| titleOfInvention | Method for preparing halogenated 3-oxocarboxylates carrying a 2-alkoxymethylidene or a 2-dialkylaminomethylidene group |
| abstract | The present invention relates to a process for preparing compounds of the formula I,n nwherein nR 1 and R 2 nare each independently from one another selected from hydrogen, fluorine, bromine, chlorine and trifluoromethyl, nR 3 nis selected from fluorine chlorine and trifluoromethyl, nR 4 nis selected from C 1 -C 4 -alkyl, and nX nis either -OR 5 or -NR 6 R 7 , wherein R 5 is selected from C 1 -C 4 -alkyl, and R 6 and nR 7 nare each independently from one another selected from C 1 -C 4 -alkyl, n nwhich comprises the reaction of a compound of the formula IIn nwith a reagent of the formula III,n nwherein the variables R 1 , R 2 , R 3 , R 4 , R 5 and X given in formulae II and III have the above defined meanings, nin the presence of a catalyst selected from Brønsted acids, ammonium salts of Brønsted acids and Lewis acids; nwherein the reaction is performed essentially in the absence of a carboxylic acid anhydride. |
