| use | 2-bromobenzonitrile is a nitrile compound. 2-Bromobenzonitrile is widely used in the production of dyes, pesticides, herbicides, etc. It is an important chemical raw material. At the same time, because the cyano group can be converted into other groups under mild conditions, such as carboxyl, amino, etc., nitrile compounds are often used as intermediates in drug synthesis. 2-Bromobenzonitrile is an organic intermediate, which can be prepared by o-bromobenzyl alcohol or o-bromobenzaldehyde in one step. Add 0.4 millimoles of o-bromostyrene, 2 millimoles of sodium nitrite, 5 milligrams of metallic iron (Ⅲ) porphyrin, and 4.5 milliliters of acetonitrile solvent to the reaction tube. Under air atmosphere, heat and stir at 70°C. Add 0.5 milliliters of formic acid drop by drop within the first 0.5 hours. After 4 hours of reaction, stop heating and stirring, cool to room temperature, obtain a crude product by a rotary evaporator, and then separate and purify by column chromatography to obtain the target product, the column chromatography eluate used was a mixed solvent of petroleum ether and ethyl acetate. The compound is a white solid with a yield of 78.49%. Bromobenzonitrile and its salts and esters are contact-killing herbicides with a certain systemic activity. They are mainly used in cereals, flax, garlic, corn, onions, sorghum and newly sown turf. After bud, prevent weeding and seedling broad-leaved weeds. Mixing with other herbicides can expand the weeding spectrum. Bromobenzonitrile and its salts and esters are contact-killing herbicides with a certain systemic activity.
