BENZOESAEUREDERIVATE UND VERFAHREN ZUR HERSTELLUNG DERSELBEN

According to the present invention there are provided fungicidal compositions comprising as active ingredient in an amount of 0.01-80% by weight a new benzoic acid derivative of the general Formula I I wherein R1 and R2 stand for hydrogen, C1-8 alkyl, C2-8 alkenyl or benzyl; R3 represents hydrogen, C1-8 alkyl or C2-8 alkenyl; R1 and R2 may be the same or different; and R3 may be identical with or different from R1 and/or R2. According to the present invention there is provided a process for the preparation of the compounds of the general Formula I which comprises esterifying 4-chloro-3,5-dinitro-benzoic acid with a saturated or unsaturated aliphatic alcohol at a temperature between 20 DEG C. and 120 DEG C.-preferably at 60 DEG -100 DEG C.-in the presence of a solvent as medium and in the presence of a catalyst, and aminating the ester thus obtained with ammonia or the corresponding primary or secondary amine at a temperature between 40 DEG C. and 100 DEG C.-preferably at 60 DEG -90 DEG C.-in the melt or in an inert solvent as medium, in the presence of an acid binding agent; or changing the order of succession of the said two steps and carrying out at first amination and thereafter esterification. A preferred representative of the compounds of the general Formula I is the n-propyl-4-diallylamino-3,5-dinitro-benzoate.
