  • Method for producing fluorine-containing substituted compound and fluorine-containing substituted compound
    Patent number: 9518074
    Abstract: A method for producing a fluorine-containing substituted compound, the method including: introducing an organofluorine compound and an organolithium compound into a microreactor provided with a flow path capable of mixing a plurality of liquids, to thereby obtain a reaction product; and introducing, into the microreactor, the reaction product and an electrophile exhibiting electrophilic effect on the reaction product, to thereby obtain a fluorine-containing substituted compound.
    Type: Grant

  • Method of producing an o-disubstituted aromatic compound, and method of producing a monosubstituted-monohaloaromatic compound
    Patent number: 7572927
    Abstract: A method of producing an o-disubstituted aromatic compound, containing: continuously conducting at least the following steps (a) to (d): (a) a step of mono-lithiating one halogen atom of an o-dihaloaromatic compound, using a first microreactor; (b) a step of making the thus-obtained monolithiated product to react with an electrophilic compound, using a second microreactor, to obtain a monosubstituted-monohaloaromatic compound; (c) a step of lithiating the other halogen atom of the o-dihaloaromatic compound, using a third microreactor; and (d) a step of making the thus-obtained lithiated product successively to react with an electrophilic compound, using a forth microreactor.
