To prepare 2-iodo-1-p-tolyl-Propan-1-one, you can follow the number method.
First, start with 1-p-tolyl-Propan-1-one and react with iodine in an alkaline medium. This is a haloform reaction variant, the methyl group of 1-p-tolyl-Propan-1-one, which is first replaced by iodine in an alkaline environment. After multi-step transformation, the target product can be obtained. During operation, 1-p-tolyl-Propan-1-one is dissolved in a suitable solvent, such as ethanol or dichloromethane, and slowly added to the solution containing iodine and alkali. Sodium hydroxide or potassium carbonate are commonly used in alkali. During the reaction, temperature control is required. Due to high temperature, or side reactions may be caused, the purity of the product will be reduced. It is often started at low temperature, such as 0-5 ° C, and gradually warmed to room temperature. The reaction process is monitored by thin-layer chromatography. When the raw material point disappears, the reaction is complete. After purification by extraction, washing, drying, column chromatography, etc., pure 2-iodo-1-p-tolyl-Propan-1-one is obtained.
Second, the Grignard reagent method can be used. First, p-toluyl Grignard reagents, such as p-toluene magnesium bromide, are prepared from p-toluene bromide (or chlorine). Magnesium chips and p-toluene bromide are mixed in anhydrous ethyl ether or tetrahydrofuran to initiate a reaction to obtain Grignard reagent solution. At the same time, ethyl propionate and iodomethane are nucleophilized to prepare the corresponding intermediates. After that, p-toluenyl Grignard reagent is slowly added to the intermediate, nucleophilic addition occurs, hydrolyzed to obtain 1-p-tolyl-Propan-1-one, and then the above halogenation reaction is reacted with iodine to obtain 2-iodo-1-p-tolyl-Propan-1-one. This process requires an anhydrous and oxygen-free environment to prevent Grignard reagent from failing. The reaction conditions of each step also need to be precisely controlled. Solvent selection, reactant ratio, reaction temperature and time length are all related to product yield and purity.
Third, using p-methylacetophenone and iodoethane as raw materials, under the action of strong bases, it can also be prepared by nucleophilic substitution reaction of carbon negative ions. Strong bases such as sodium hydride or potassium tert-butyl alcohol make p-methylacetophenone form carbon negative ions, attack the carbon of iodoethane, form carbon-carbon bonds, and obtain 1-p-tolyl-Propan-1-one precursor, and then halogenate to obtain the target. In this path, the strong base activity is high, the operation needs to be cautious, the side reaction needs to be prevented, and the sealing requirements of the reaction equipment are high, avoiding air and water vapor interference.
