Abstract:
PROBLEM TO BE SOLVED: To obtain a new compound having herbicidal property and useful as an active ingredient of a herbicide preferably in the form of solution capable of directly scattering, emulsion, paste, oil dispersion, etc. SOLUTION: This compound is shown by formula I [X is O or S; R1 is H, hydroxyl, a 1-6C (substituted)alkyl or the like; R2 and R3 are each nitro, cyano, a halogen, H or the like; but in the case where X is O and R2 and R3 are each phenyl, R1 is not phenyl or H and all of R1 to R3 are not methyl or the like], for example N-isopropylthiophene-3,4-carboximide. For example, a compound of the formula I can be produced by reacting (A) a carboxylic acid anhydride of formula II with (B) an amine of the formula H2N-R1 in a molar ratio of the component A to the component B ranging from 0.9 to 1.5, (C) if necessary in the presence of an acid catalyst (ex. aromatic sulfonic acid), in a solvent at 0-150 deg.C, preferably 20-100 deg.C, preferably while removing a preparing reaction water or the like.
Abstract:
PROBLEM TO BE SOLVED: To obtain a new benzoyl derivative capable of exterminating weeds without damaging raised plants. SOLUTION: This new compound is shown by formula I [L and M are each H, a 1-6C alkyl, 2-6C alkenyl, 2-6C alkynyl or the like; Y is C=O, C=N-R3 (R3 is H, a 1-6C alkyl or the like or the like; X is CR12R13, NR23 (R12 and R13 are each H, a 1-6C alkyl or the like; R23 is H, a 1-6C alkyl or the like) or the like; Q is a group of formula II (R15, R16, R18 and R20 are each H or a 1-4C alkyl; R19 is H, a 1-4C alkyl or the like; R17 is H, a 3-4C cycloalkyl or the like) or the like; (n) is 0-2], e.g. 2-(8-methyl-4-ethoxy-1,1-dioxothiochroman-7- carbonyl)-cyclohexane-1,3-dione. The compound of formula I is obtained, for example, by acylating a starting material of formula II with a chloride of formula III followed by rearrangement of the resulting acrylated product in the presence of a catalyst.
