  • Process for the preparation of 1-alkyl and 1-aryl-5-pyrazolecarboxylic acid derivatives
    Patent number: 8586753
    Abstract: The present invention relates to a process for the preparation of 1-alkyl- or 1-aryl-substituted 5-pyrazolecarboxylic acid derivatives comprising the reaction of substituted 1,3-dioxolanes and 1,4-dioxanes with alkyl- or arylhydrazines to give 1-alkyl- or 1-aryl-substituted dihydro-1H-pyrazoles, and their further reaction to give 1-alkyl- or 1-aryl-substituted 5-pyrazolecarboxylic acid derivatives, which can be used as valuable intermediates for producing insecticidally effective anthranilamides.
    Type: Grant
    Filed: December 15, 2010
    Date of Patent: November 19, 2013
    Assignee: Bayer CropScience AG
    Inventors: Sergii Pazenok, Norbert Lui, Igor Gerus
  • Dioxolane and dioxane derivatives and a process for their preparation
    Patent number: 8222435
    Abstract: The present invention relates to novel acylmethylene-1,3-dioxolanes and acylmethylene-1,4-dioxanes of the general formula (I) in which R1, R2, R3 and n have the meanings given in the description, and also a novel process for their preparation. Acylmethylene-1,3-dioxolanes and acylmethylene-1,4-dioxanes are important intermediates for the preparation of pyrazoles and anthranilamides, which can be used as insecticides.
