| titleOfInvention | Preparation of 4-benzoylpyrazole-type compound |
| abstract | PURPOSE: To prepare the titled substance from an inexpensive raw material, in a short time, easily, in high yiekd, by reacting a benzotrichloride-type compound, a benzoic acid-type compound, and a pyrazolone-type compound in the presence of a catalyst. n CONSTITUTION: A compound of formula I (X and Y are H or halogen), a compound of formula II and a compound of formula III (R is lower alkyl) are made to react together in the presence of a catalyst to obtain a compound of formula IV (Z is H or metal atom). The catalyst is a metal halide or an acid such as sulfuric acid, phosphoric acid, perchloric acid, etc., especially pref. magnesium chloride or zinc chloride. The reaction is carried out if necessary in a solvent. The solvent is pref. the one having a bailing point of ≥130°C, e.g. nitrobenzene, dichrlorobenzene, etc. The amount of the compound of formula I is equimolar amount of the compound of formula II, and that of the compound of formula III is 1mol/mol of the sum of the compounds of formula I and II. n COPYRIGHT: (C)1982,JPO&Japio |
