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.
