Abstract:
A composition, comprising:a. one or more compounds of formula I, with the stereochemistry depicted: wherein:1. A is C-R5; 2. R1 and R2 are different and are independently selected from H, (C1-C6)alkyl, (C2-C6)alkenyl, (C2-C6);,alkynyl, and halo(C1-C6)alkyl and R2 is stereochemically larger than R1; 3. R3, R4, and RG) are independently selected from H, halo, (C1-C6)alkyl, (C2-C6)alkenyl, (C1-C6)alkynyl, halo(C1-C6)alkyl, (C1-C6)alkoxy, halo(C1-C6)alkoxy, cyano, nitro, â€”CR6=NOR7, â€”NR8R9, CONR1OR1 1, and â€”NH-CO-OR12 wherein R6 is selected from H, (C1-C6)alkyl, (C2-C6)alkenyl, and (C2A-C6)alkynyl, R7 is selected from H, (C1-C6,)alkyl, (C2-C6)alkenyl, (C2-C6)alkynyl, and (C1-C6)alkylcarbonyl, R8 and R9 are independently selected from H, (C1-C6)alkyl, and (C1-C6)alkylcarbonyl, R10and R11 are independently selected from H and (C1-C6)alkyl; and R12 is seleceted from H, (C1-C6)alkyl, (C2-C6)alkenyl, and (C2-C6)alkynyl; 4. X, Y, and Z are independently selected from H, halo, cyano, thiocyano, isothiocyano, and (C1-C4)alkylsulfonyloxy; provided that X, Y, and Z are not all H; and b. an agronomically acceptable carrier; wherein the composition is predominantly free of the compound of formula I wherein R1 is stereochemically larger than R2;.
