Definitions
- the present invention relates to a novel process for the preparation of dithiine tetracarboximides.
- Dithiine tetracarboximides as such are already known. Likewise, it is known that these dithiine-tetracarboximides can be used as anthelminthicides against internal parasites of animals, in particular nematodes, and have insecticidal activity (cf US 3,364,229). In addition, it is known that certain dithiine-tetracarboximides have antibacterial activity and have some activity against human mycoses (compare II Farmaco 2005, 60, 944-947). Furthermore, it is known that dithiine-tetracarboximides can be used as pigments in electrophotographic photoreceptors or as dyes in paints and polymers (cf JP-A 10-251265, PL-B 143804). Dithiine tetracarboximides of the formula (I)
- R 1 and R 2 are identical or different and are hydrogen, for optionally mono- or polysubstituted by halogen, -OR 3 , -COR 4- substituted Ci-Cs-alkyl, optionally mono- or polysubstituted by halogen, Ci-C i-alkyl or Ci C 1 -C 6 -haloalkyl-substituted C 3 -C 7 -cycloalkyl, in each case optionally monosubstituted or polysubstituted by halogen, C 1 -C 6 -alkyl, C 1 -C 4 -haloalkyl, -COR 4 or sulphonylamino, substituted aryl or aryl- (C 1 -C 4 ) alkyl),
- R 3 represents hydrogen, Ci-C 4 alkyl, Ci-C4-alkylcarbonyl or optionally mono- or polysubstituted by halogen, Ci-C 4 alkyl or Ci-C 4 haloalkyl substituted aryl,
- R 4 is hydroxy, C 1 -C 4 -alkyl or C 1 -C 4 -alkoxy
- succinic anhydride of the formula (V) is reacted in a first stage with an amine of the formula (III), if appropriate in the presence of a diluent. Subsequently, the succinic monoamides of the formula (VI) thus obtained are reacted for 6 hours with a large excess of thionyl chloride in the presence of dioxane as diluent at room temperature, the dithiine-tetracarboximides of the formula (I) being finally obtained in a series of numerous reaction steps.
- the dithiine-tetracarboximides are optionally isolated directly from the reaction mixture or after addition of water by filtration.
- the dithiine diisoimides of the formula (VII) may possibly be isolated before they are converted into the dithiine tetracarboximides of the formula (I).
- This preparation method of the dithiine-tetracarboximides of the formula (I) can be illustrated by the following scheme:
- a disadvantage of this process is the long reaction time and the result that either the yields obtained usually do not exceed about 30-40% of theory or the purities of the isolated products are insufficient (see Comparative Examples).
- the reaction mixture in an aqueous workup of the reaction mixture is disadvantageous that thereby large amounts of thionyl chloride are destroyed; The resulting gases (SO2 and HCl) must be disposed of.
- Another disadvantage is the fact that experience shows (see Comparative Examples), the product is not obtained in a fraction. Rather, it is often so that after an initial product isolation by filtration from the filtrate after prolonged standing (for example, overnight), more product precipitates, which must be isolated again by filtration. Sometimes this process needs to be done again. This way of working is very cumbersome and time consuming.
- R is R 1 or R 2 ,
- M is a cation selected from the group of alkali metals, alkaline earth metals, transition metals and metals, and
- m is 1, 2, 3 or 4, reacted with an excess of thionyl chloride, if appropriate in the presence of a diluent, then the excess of thionyl chloride removed and the product mixture thus obtained in a second stage in a mixture of an organic solvent, water and a phase Trans - Ferkatalysator converted into the dithiine tetracarboximides of the formula (I).
- the dithiine-tetracarboximides of the formula (I) can be obtained in higher yield, shorter time and better purity.
- the product mixture obtained in the first step of the process according to the invention also already contains dithiine-tetracarboximides of the formula (I), but the main components are polysulfides of the formula (IX) and, depending on the work-up method, also thiosulfonic acid derivatives of the formula (VIII)
