    摘要: The invention relates to a novel method for producing dithiine tetracarboximides of the general formula (I), where R
    1 and R
    2 have the meanings given above, characterized in that succinic acid monoamides of the formula (VI), where R is R
    1 or R
    2 , is reacted with an excess of thionyl chloride, optionally in the presence of a thinner, the excess of thionyl chloride is subsequently removed, and the product mixture thus obtained is transformed into the dithiine tetracarboximide of the formula (I) in a second state in an organic solvent.
