| titleOfInvention | Remote halogenated alkyl ketone with HX as halogen source and its synthesis method |
| abstract | A far-end halogenated alkyl ketone using HX as a halogen source and a synthesis method thereof, adding a cycloalkyl peroxy alcohol and a copper acetate catalyst under a nitrogen atmosphere, then adding HCl, HBr, and HI solution as halogens, and stirring at room temperature; after the reaction is completed, Add a sufficient amount of water extraction reaction solvent N-methylpyrrolidone, wash with saturated brine, and finally dry the organic phase with anhydrous sodium sulfate, concentrate the organic phase under reduced pressure, and remove the solvent; The organic phase is subjected to column chromatography to obtain the target product The present invention uses industrial bulk raw materials HCl, HBr and HI solution as halogen sources, realizes the radical halogenation of C-C bond cleavage, and obtains remote halogenated alkyl alkyl ketone compounds with higher yield. The by-product of the reaction is water, which reduces environmental pollution and greatly improves industrial production efficiency. |
