    Abstract: A process is described for preparing 3-phenyl(thio)uracils or 3-phenyldithiouracils of the formula I, by reacting a phenyl iso(thio)cyanate of the formula II with an enamine of the formula III and, if appropriate, in a further step, the resulting 3-phenyl(thio)uracil or 3-phenyldithiouracil of the formula I where R1=R1a, when R1=hydrogen, is reacted with an aminating agent of the formula IV to give 3-phenyl(thio)uracils or 3-phenyldithiouracils of the formula I where R1=amino where the variables R1, R1a, R2, R3, R4, X1, X2, X3, Ar, A and L1 are each as defined in claim 1.

    Abstract: The invention relates to a method for producing o-chloromethyl benzoic acid chlorides of formula (I), in which R 1 to R 4 can be the same or different and represent hydrogen C 1 -C 4 alkyl, halogen or trifluoromethyl, by reaction benzo condensed lactones of formula (II), in which R 1 to R 4 have the above-mentioned meaning, with thionyl chloride. The inventive method is characterized in that the reaction is carried out in the presence of catalytic quantities of a Lewis acid and in the presence of catalytic quantities of a phosphine derivative.
