4,5-Carbon dioxide-2-alkynyl acetone, this compound is more special, and the preparation method also has its own details, which are described in detail below.
Take an appropriate amount of acetylene first, put it into the reaction bottle containing liquid ammonia, and slowly add sodium metal in this low temperature environment. Sodium reacts with acetylene to generate sodium acetylene. This reaction needs to be handled carefully. Due to the volatility of liquid ammonia and the activity of sodium metal, it needs to be treated with caution to prevent accidents.
After the formation of sodium acetylene, the temperature of the reaction bottle is slightly increased, and then halogenated acetone containing a specific substituent is slowly added dropwise. The halogenated acetone atom undergoes a nucleophilic substitution reaction with the alkynyl group of sodium acetylene, and then the acetone derivative containing the alkynyl group is formed. During the reaction process, it is necessary to monitor the ratio of the reaction temperature to the reactant at all times, so that the reaction proceeds in the direction of generating the target product.
Then, the introduction step of carbon dioxide is carried out. The product obtained by the above reaction is transferred to another reaction device, and under appropriate pressure and temperature conditions, carbon dioxide gas is introduced. Carbon dioxide reacts with acetone derivatives containing alkynyl groups. The reaction mechanism is relatively complex, involving electron transfer between molecules and the rearrangement of chemical bonds, and finally generating 4,5-carbon dioxide-2-alkynyl acetone. After the
reaction is completed, the product needs to go through the purification process. Column chromatography can be used to use a suitable silica gel as the stationary phase and a specific proportion of organic solvent as the mobile phase to separate the product from the impurities generated during the reaction. Or use the method of recrystallization, select a suitable solvent, dissolve the product in it, and then slowly cool down or evaporate the solvent to precipitate the product in crystal form, and then achieve the purpose of purification. The whole preparation process requires the experimenter to be familiar with various chemical operations and precisely control the reaction conditions in order to obtain 4,5-carbon dioxide-2-alkynyl acetone with high yield and purity.
