| Abstract: | Trans-2,2-dimethyl-3-(2,2-dichloroethenyl)cyclopropanecarbonyl chloride, which is animportant intermediate for insecticides, is obtained by isomerization of the cis/trans-mixture with4- (N,N-dimethylamino) pyridine (DMAP) in the presence or absence of halogen compounds ingood yield. |
| Keywords: | Permethric acid chloride dimethylaminopyridine conversion |
