Method of obtaining piretrod derivatives |
| abstract |
Compounds of formula (I> <IMAGE> wherein R<2> stands for hydrogen or -CN group R<3> stands for substituted, mono- or bicyclic group optionally containing hetero atom or alkyl having 1-4 carbon atoms, R<4> stands for hydrogen atom or alkyl having 1-4 carbon atoms, R<5> stands for hydrogen atom or alkyl having 1-4 carbon atoms, R<6> stands for substituted alkyl having 1-4 carbon atoms or <IMAGE> wherein R<1> stands for halogen atom or methyl, R<7> stands for hydrogen atom, R<6> and R<7> taken together stands for substituted or unsubstituted alkylene having 1-4 carbon atoms, are prepared by reacting a salt of the corresponding carboxylic acid or a salt of its alkyl ester with a chloroformate and eliminating carbon dioxide from the unstable mixed anhydride thus obtained. The compounds prepared according to the invention are obtained in highly pure quality and can be used as insecticides without further purification. |
