【Abstract】 Dichlorochrysanthemate is the important intermediate of pyrethroid insecticides.The primary synthetic methods of its precursor 3-methyl-2-butene-1-ol were reviewed starting from different raw materials.The different results obtained from different synthetic routes were summarized,and the feasibilities of different methods were also discussed.The synthesis method of 3-methyl-2-butene-1-ol using isobutene as starting material througt Prins condensation was introduced particularly because of its available raw materials,two reaction steps and few byproducts,suggesting that this should be the most important industrial synthetic method.更多还原
