    摘要: Disclosed is a method of producing an organic compound. The method uses a metathesis catalyst in a coupling reaction of an olefin. The method comprises the steps of introducing the olefin into a container; either placing the container under vacuum or bubbling a gas through the olefin; adding an additive with the olefin; mixing the olefin and the additive, the mixing creating a mixture; adding an amount of the metathesis catalyst to the mixture, the amount being less than about 100 ppm by weight of the mixture; and optionally heating the mixture to a temperature, the temperature being greater than room temperature.

    摘要: Disclosed is a method for preparing a dinitrile compound. The method includes reacting an alcohol compound with a nitrile compound having a terminal carbon-carbon unsaturated bond under anhydrous conditions. A potassium alkoxide having 1 to 5 carbon atoms is used as a catalyst in the course of the reaction. According to the method, a high-purity dinitrile compound can be prepared in a simple manner within a short reaction time indicating high productivity.
