| titleOfInvention | A kind of preparation method of benzoyl area kind derivative |
| abstract | The present invention relates to a kind of preparation method of benzoyl area kind derivative, particularly substitute phosgene, trichloromethylchloroformate or oxalyl chloride directly and the chemical synthesis process of substituted aniline and substituted benzamide prepared in reaction benzoyl area kind derivative with two (trichloromethyl) carbonic ethers.In organic solvent,, obtain described benzoyl area kind derivative by the substituted benzamide shown in the substituted aniline shown in the formula (II) and two (trichloromethyl) carbonic ethers and the formula (III) in 20～200 ℃ of reaction 1～20h.That advantage of the present invention is is simple to operate, reactions steps is few, solvent loss is little, environmental friendliness, production safety is reliable, production cost is low, the reaction yield height, and toxicity is little, and corrodibility is little, has big industrialization potentiality and economic results in society. |
