Efficient Isomerization for Preparing thans-2,2-Dimethyl-3-(2,2-dichloroethenyl) cyclopropanecarbonyl Chloride
摘要:
Traps-2,2-dimethyl-3一(2,2-dichloroethenyl) cyclopropanecarbonyl chloride, which is an important intermediate for insecticides, is obtained by isomerization of the cis/traps-mixture with 4- (N,N-dimethylamino) pyridine (DMAP) in the presence or absence of halogen compounds in good yield.
