| titleOfInvention | A kind of new method synthesizing Cyclopropyl Bromide |
| abstract | The present invention relates to a kind of new method synthesizing Cyclopropyl Bromide: ethylene-acetic acid is first reacted with carbonyl dimidazoles generation ring propionyl imidazole; subsequently this intermediate and trichlorobromomethane are mixed; maintain to be slowly added dropwise after oxidant carries out free radical deacidification bromo-reaction under 10 DEG C to 140 DEG C conditions and obtain Cyclopropyl Bromide crude product, after simple atmospheric distillation, obtain the product of purity more than 99%.This reaction condition is gentle, and agents useful for same conventional inexpensive is easy to get, it is to avoid the use of former employing toxic articles mercury oxide, is suitable for industrial amplification production. |
