Adding a certain compound to certain chemical reactions, such as: 6940-76-7, name is 1-Chloro-3-iodopropane, belongs to iodides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 6940-76-7, COA of Formula: C3H6ClI
General procedure: In a round flask 300 mg (1.18 mmol) of compound 1 are weighed and placed in an inert atmosphere with a magnetic stirrer. Then, 3 ml of dry THF are added and the system is cooled to 0 C. Then 1.2 equivalents of LDA are added and left in an ice bath for 10 minutes. The ice bath is removed and left under constant stirring for 2 hours. The round flask is cooled again to 0 C and 1,3-chloroiodopropane is added using a syringe previously purged with nitrogen. The ice bath is removed and the reaction is followed by TLC until the consumption of the starting material (1). Once the reaction (approximately 2.5 h) is finished, 0.5 ml of a saturated NH4OH solution is added and an extraction with 5 ml of dichloromethane is carried out in triplicate, the organic phase is collected and dried with anhydrous sodium sulfate, once dried the organic phase is distilled under vacuum. The purification is carried out by a chromatographic column using silica gel as a stationary phase and a mixture of Hexane and ethyl acetate in a proportion of 95:5. A pale yellow oil is obtained in all cases.
