| titleOfInvention | Synthesis method of o-bromobenzotrifluoride |
| abstract | The invention provides a synthesis method of o-bromobenzotrifluoride, which comprises the following steps: A) mixing o-amino benzotrifluoride, hydrobromic acid and sodium nitrite for reaction to obtain a diazonium salt solution; B) and mixing the diazonium salt solution with cuprous bromide and hydrobromic acid for reaction to obtain o-bromobenzotrifluoride. The invention overcomes the defects of high cost, more product impurities and the like in the prior art, adopts cheap and easily obtained raw materials, has good solvent recovery effect, high yield and high product content, synthesizes the o-bromobenzotrifluoride by one step, and has less meta-isomer and para-isomer and low production cost compared with other routes. |
