| titleOfInvention | Synthesis method of 3-bromocyclohex-2-enone |
| abstract | The invention discloses a synthesis method of 3-bromocyclohex-2-enone, and belongs to the technical field of drug intermediate preparation. The synthesis method includes the steps that 1,3-cyclohexanedione, triphenylphosphine and carbon tetrabromide are dissolved in organic solvent under protection of inert gas, the mixture is reacted for 2-12 h at 0-70 DEG C, a quenching reaction and filtration are performed, and then 3-bromocyclohex-2-enone is obtained through column chromatography isolation or reduced pressure distillation. The synthesis method is safe and mild, no liquid bromine reagent is used, and high-yield 3-bromocyclohex-2-enone is obtained through the low-cost raw materials. Safety is easy to control in the synthesis process, equipment requirements are low, and the synthesis method is suitable for industrial production. |
