摘要

The invention relates to a herbicide safener of the formula I shown in Claim 1, in which R1 and R2 are H or (C1-C4)-alkyl, X is O or S or NR4, where R4 is H, (C1-C6)-alkyl, (C1-C6)-alkoxy or optionally substituted phenyl, A is (C1-C6)-alkylene, (C4-C8)-alkenylene, (C4-C8)-alkynylene, (C3-C8)-cycloalkylene or (C3-C8)-cycloalkenylene, R3 is (C3-C6)-alkenyloxy, (C3-C6)-alkynyloxy, (substituted) phenyl-(C1-C4)-alkoxy, R5R6R7Si-, R5R6R7Si-O-, R5R6R7Si-(C1-C4)-alkoxy, (C3-C6)-alkenyloxycarbonyl, (C3-C6)-alkynyloxycarbonyl, (substituted) phenyl-(C1-C4)-alkoxycarbonyl, R5R6C=N-O-CO-, R5R6C=N-O-, R5R6N-O-, R5R6C=N-, (C2-C6)-alkenylcarbonyl, (C2-C6)-alkynylcarbonyl, 1-(hydroxyimino)-(C1-C6)-alkyl, 1-[(C1-C4)-alkylimino]-(C1-C6)-alkyl, 1-[(C1-C4)-alkoxyimino]-(C1-C6)-alkyl, a radical of the formula R8O-CH(OR9)- or R8O-CH(OR9)-(CH2)n-O-, in which n is 0, 1 or 2, or an alkoxy radical of the formula R8O-CHR10-CH(OR9)-(C1-C4)-alkoxy, (substituted) (C1-C6)-alkylcarbonyloxy, (C2-C6)-alkenylcarbonyloxy, (C2-C6)-alkynylcarbonyloxy, (C1-C6)-alkylcarbonylamino, (C2-C6)-alkenylcarbonylamino, (C2-C6)-alkynylcarbonylamino, (substituted) phenylcarbonyloxy, (substituted) phenylcarbonylamino, (substituted) phenyl-(C1-C4)-alkylcarbonylamino, aminocarbonyl, (C1-C6)-alkylaminocarbonyl, (C1-C6)-dialkylaminocarbonyl, (C3-C6-alkenylaminocarbonyl, (C3-C6)-alkynylaminocarbonyl, (C1-C6)-alkoxycarbonylamino, (C1-C6)-alkylaminocarbonylamino or (C1-C6)-alkylthiocarbonyl, (C3-C6)-alkenylthio, (C3-C6)-alkynylthio, and R5, R6, R7 are H, (C1-C4)-alkyl or (substituted) phenyl, or R5 and R6 together with the N or C atom linking them is a (substituted) ring having 3 to 7 ring atoms, R8 and R9 are (C1-C4)-alkyl, or R8 and R9 together are a straight-chain or branched (C1-C4)-alkylene bridge, and R10 is H or (C1-C4)-alkyl.
