Introduction | cyclopropyl methyl ketone is an organic intermediate, which can be made from α-acetyl-γ-butyrolactone, 5-chloro-2-pentanone was prepared first and then obtained by ring closure. Cyclopropylmethyl ketone can be used to prepare 2-chloro-1-(1-chlorocyclopropyl) ethanone, an intermediate of propylthioconazole. |
properties | cyclopropyl methyl ketone is a colorless transparent liquid, solubility: it has a certain solubility in water, miscible with alcohol ether. |
Application | cyclopropyl methyl ketone is an important organic raw material and intermediate. In medicine, it is mainly used for the synthesis of anti-AIDS drugs by fluviram and ileremin; In pesticide, it is mainly used for the synthesis of bactericides, cyromazine and cycloconazole. |
synthesis method | There are two synthesis processes of cyclopropyl methyl ketone, one of which is: the raw material of γ-butyrolactone is more common, prepared by acetylation, hydrolysis, decarboxylation, chlorination, cyclization, refining. |
Use | for pharmaceutical and pesticide intermediates |
production method | can be prepared from 5-bromo-2-pentanone by dehydrobromination or by the action of cyclopropanecarboxylic acid nitrile and methyl magnesium bromide |
