Bicyclic heteroaryl compounds, processes for their prepartion, compositions comprising them, and their use as safeners. Compounds of the formula (I) and salts thereof Image (I) in which W1 is N or CR* and W2 is O, S, NH, NR**, N=N, N=CR* or CR*=N and the total of the hetero ring atoms of the groups W1 and W2 is 2 or 3, and A is a divalent hydrocarbon radical having 1 to 12 carbon atoms, B1 and B2 are carboxyl, or derivatives thereof, or formyl or derivatives thereof, or an acyl radical of the formula -CO-R, in which R is an aliphatic, arali- phatic or aromatic radical which can additionally comprise other functional groups and can have a total of up to 24 carbon atoms, n is 0 or 1, R* in each case independently of the other radicals R* is H, Hal, (C1-C8)-haloalkyl, (C1-C8)-haloalkoxy, (C1-C8)-alkyl, (C1-C8)-alkoxy, NO2, NH2 or amino which is substituted by 1 or 2 radicals selected from the group consisting of (C1-C4)-alkyl and acyl having 1-10 carbon atoms, or CN, (C1-C8)-alkylthio or (C1-C8)-alkylsulfonyl or (substituted) phenyl, and R** is (C1-C8)-alkyl, (C1-C8)-haloalkyl, (C1-C8)-alkyl- thio, (C1-C8)-alkoxy, (C1-C8)-haloalkoxy, (C1-C8)- alkylsulfonyl, cyano-(C1-C8)-alkyl, [(C1-C8)-alkyl]- carbonyl or [(C1-C8)-alkoxy]-carbonyl and which are defined in greater detail in claim 1 are suitable according to the invention as safeners for reducing phytotoxic effects of crop protection products (for example herbicides) on crop plants. The compounds, some of which are novel and some of which are known, can be prepared analogously to known processes.
