The present invention relates to a process for preparing difluoromethyl-substituted pyrazol-4-ylcarboxylates of the formula I in which R1 is C1-C8-alkyl, C3-C8-cycloalkyl, C1-C4-alkoxy-C1-C4-alkyl, etc.; and R2 is hydrogen, C1-C4-alkyl, benzyl or phenyl, wherein a) a compound of the general formula II in which X is fluorine, chlorine or bromine, R1 has one of the meanings given above and R4 is C1-C8-alkyl, C3-C8-cycloalkyl, C2-C8-alkenyl, benzyl or phenyl, is reacted with a silane compound of the general formula R3nSiCl(4-n) in which n is 1, 2 or 3 and the substituents R3 are independently of one another selected from the group consisting of C1-C8-alkyl and phenyl and with a metal selected from the metals of groups 1, 2, 3, 4 and 12 of the Periodic Table of the Elements having a redox potential of less than −0.7 V, based on a normal hydrogen electrode (at 25° C. and 101.325 kPa); and b) the reaction mixture from step a) is reacted with a compound of the general formula III R2HN—NH2   (III) in which R2 has one of the meanings given above.
