  • Chlorobenzene compound production method
    Patent number: 11780813
    Abstract: The present invention provides a new production method for a chlorobenzene compound. Specifically, the present invention provides a production method in which the compound represented by formula (1) (in the formula, X1 represents a halogen atom) and chlorine are reacted in the presence of a Brønsted acid, thereby obtaining the chlorobenzene compound represented by formula (2) (in the formula, X1 represents the same as above).
    Type: Grant
    Filed: January 29, 2020
    Date of Patent: October 10, 2023
    Assignee: SUMITOMO CHEMICAL COMPANY, LIMITED
    Inventors: Junichi Ishikawa, Tohru Inoue, Takayuki Wakamatsu, Miyuki Iguchi
  • Pyridone compound production method
    Patent number: 11760724
    Abstract: The present invention provides an effective production method for a pyridone compound. More specifically, the present invention provides a production method comprising: a step of reacting the compound represented by formula (1) (in the formula, X1 and X2 each independently represent a halogen atom, R1 represents a hydrogen atom, an amino group, or a group represented by NHCOR2, and R2 represents a C1-C5 alkyl group) with 4 to 10 times by mass, with respect to the compound represented by formula (1), of the compound represented by formula (2) (in the formula, R2 represents the same as described previously), in the presence of at least one of a tri(C1-C8 alkyl)amine and an alkali metal acetate, at a temperature of 100° C.
