- 1 - N-Sulfonyl-imino-thiocarbonic acid diesters as herbicide antagonists for the protection of rice crops Abstract N-Sulfonyl-imino-thiocarbonic acid diesters of the formula I Image (I) wherein n is zero, 1, 2 or 3, R is halogen, cyano, nitro, a radical -Y-C1-C4-alkyl, -Y-C3-C6-alkenyl, -Y-C3-C6-alkynyl, -Y-phenyl or -Y-aralkyl, each unsubstituted or substituted by halogen, cyano, nitro, C1-C4-alkoxy, C1-C4-alkoxy- carbonyl, carbamoyl, sulfamoyl, C1-C4-mono- or dialkylcarbamoyl, C1-C4-mono- or dialkylsulfamoyl, or is a radical -COOR3, -NR3R4, -CONR3R4, -NHCONR3R or -SO2NR3R4, or two adjacent R's together form a 3- or 4-membered, saturated or unsaturated hydrocarbon chain, the chain members of which can be replaced once by oxygen or sulfur and/or once to three times by nitrogen, R1 and R2 independently of one another are each a C1-C4- alkyl, C3-C6-alkenyl, C3-C6-alkynyl, phenyl or aralkyl group, which can be unsubstituted or sub- stituted by halogen, cyano, nitro, C1-C4-alkyl, C1-C4-haloalkyl or C1-C4-alkoxy, or one of R1 and R2 can also be hydrogen or can form a 5- or 6- membered, saturated or unsaturated heterocycle which - 2 - is bound by way of a carbon atom, contains 1-3 hetero atoms and can also be annularly-linked to a benzene ring, and which can be substituted by halogen and/or methyl, R3 is a C1-C4-alkyl, C3-C6-alkenyl, C3-C6-alkynyl or C3-C6-cycloalkenyl group, each of which can be sub- stituted by halogen, cyano, nitro or C1-C4-alkyl, R4 is hydrogen, the same as R3, or a phenyl or aralkyl group which can be substituted by halogen, cyano, nitro, C1-C4-alkyl, C1-C4-haloalkyl or C1-C4-alkoxy, or R3 and R4 together with the nitrogen atom to which they are bound form a 5- or 6-membered, saturated or unsaturated heterocycle which can also contain oxygen, sulfur, nitrogen or a methylimino group as ring member, X is oxygen or sulfur, and Y is the direct bond or an oxygen, sulfur, sulfinyl, sulfonyl, imino- or methylimino bridge are suitable as herbicide antagonists for protecting rice crops from phytotoxic damage which can occur as a result of herbicides. The N-sulfonyl-imino-thiocarbonic acid diesters are in part known.
