| titleOfInvention | A kind of method for reducing carbonyl to alcohol under room temperature air atmosphere |
| abstract | The invention belongs to the field of organic synthesis, and relates to a method for reducing carbonyl to alcohol in an air atmosphere at room temperature. The specific steps include: first, adding methanol, a catalyst and a carbonyl compound into a reaction flask, slowly adding silane into the reaction flask, and stirring magnetically. , the reaction is carried out for 10 minutes to 8 hours in an air atmosphere at room temperature, and a mixture containing a benzyl compound is obtained after the reaction is completed. Next, the mixture containing the benzyl compound is extracted with dichloromethane as an extractant, and the organic phases are combined, washed with deionized water as a detergent, dried over anhydrous sodium sulfate, and evaporated to remove the solvent to obtain a crude product benzyl alcohol compound. Finally, the crude product benzyl alcohol compound is separated and purified by column chromatography to obtain pure benzyl alcohol compound. The reducing agent adopted in the invention has low toxicity, is clean and environment-friendly, can avoid the use of precious metal catalysts, and has low cost; the reaction conditions are mild, and good selectivity and high yield can be obtained. |
