| Abstract: | 2- chloro- 5 -methyl pyridine is an important intermediate for producing pesticides with high efficiency, low toxin and low residue, such as imidacloprid and fluazifop - p - butyl. Seven primary synthetic methods for 2 - chloro - 5 -methyl pyridine were summarized,including 3 -methylpyridine oxidation ,3 -methylpyridine chlorination in one- step, diazotization, molten salt, cyclization of benzylamine, miscellaneous cyclization, and pyridine methods. Application of 2 - chloro - 5 - methyl pyridine as intermediates in agrochemicals and bioebemicals was briefly introduced. Progress and development trend of 2 - chloro - 5 - methyl pyridine study were also described. |
