| titleOfInvention | The preparation method of 5 [(4 chlorphenyl) methyl] 2,2 cyclopentanone dimethyls |
| abstract | The present invention relates to a kind of preparation method of 5 [(4 chlorphenyl) methyl] 2,2 cyclopentanone dimethyls, the problem of relatively low product yield in the prior art, complex operation, larger environmental pollution is mainly solved.The present invention is by using a kind of 5 [(4 chlorphenyl) methyl] 2, the preparation method of 2 cyclopentanone dimethyls, with 1 [(4 chlorphenyl) methyl] 3, the oxo-cyclopentane methyl formate of 3 dimethyl 2 or 1 [(4 chlorphenyl) methyl] 3, the oxo-cyclopentane Ethyl formate of 3 dimethyl 2 is raw material, in ionic liquid, decarboxylic reaction is carried out in the case where reaction temperature is 100 180 DEG C, obtain 5 [(4 chlorphenyl) methyl] 2, the technical scheme of 2 cyclopentanone dimethyl products preferably solves above mentioned problem, available for 5 [(4 chlorphenyl) methyl] 2, in the preparation of 2 cyclopentanone dimethyls. |
