| titleOfInvention | A kind of preparation method of the fluoro- 3- Trifluoromethoxyphen-l pinacol borate of 4- |
| abstract | The invention discloses a kind of preparation methods of the fluoro- 3- Trifluoromethoxyphen-l pinacol borate of 4-, and this method comprises the following steps: using adjacent fluorine trifluomethoxybenzene as starting material, the fluoro- 4- nitro -2- trifluomethoxybenzene of 1- is made by nitration reaction；Then, the fluoro- 4- nitro -2- trifluomethoxybenzene of 1- passes through reduction reaction, and the fluoro- 4- amido -2- trifluomethoxybenzene of 1- is made；Finally, the fluoro- 3- Trifluoromethoxyphen-l pinacol borate of the 4- is made in the fluoro- 4- amido -2- trifluomethoxybenzene diazotising of 1-.The method of the present invention technical process route is short, easy to operate, reaction condition is mild and easy to control, and cost is relatively low, it is easy to accomplish industrialization, avoid the generation that existing technique is directly catalyzed C-H activation isomers and by-product, it also avoids using expensive catalyst, product is easy to purify, and yield is higher. |
