  • Patent number: 11858873
    Abstract: Disclosed is a method for continuously synthesizing a propellane compound. The method includes the following steps: using 1,1-dibromo-2,2-bis(chloromethyl)cyclopropane or a derivative thereof as a raw material to form a ring with a lithium metal agent by a continuous reaction, so as to synthesize the propellane compound. A technical scheme of the present disclosure is applied, and a continuous reaction device is used.

  • Publication number: 20220144744
    Abstract: Provided is a continuous synthesis method for 1,1?-bicyclic[1.1.1]pentane-1,3-diethyl ketone compounds. The continuous synthesis method comprises: under the irradiation of a light source, continuously conveying raw material A and raw material B to a continuous reaction device for a continuous photochemical reaction to obtain 1,1?-bicyclic[1.1.1]pentane-1,3-diethyl ketone compounds, and controlling the reaction temperature in the continuous reaction device by a temperature control device during the continuous photochemical reaction. A propellane with substituents, as a reaction raw material, is subjected to the above photochemical reaction in the continuous reaction device to reduce the probability of its slow decomposition and deterioration under the irradiation, and greatly improve the conversion rate of the reaction material and product yield.
