Zusammenfassung: | Halogenated Esters Compounds of formula: wherein Q represents a lower alkoxy group containing up to six carbon atoms, one of R1 and R2 represents a group of formula: W(CF2)mwhere W represents an atom of hydrogen, fluorine, or chlorine and m has a value of one or two, and the other of R1 and R2 represents an atom of fluorine , chlorine or bromine, or a group formula: where each of X, Y and Z independently represents an atom of hydrogen, fluorine, or chlorine; and W' and W" each represent fluorine, chlorine or bromine, provided that W' is bromine when R2 is bromine. The compounds are useful as intermediates in the preparation of insecticides. |
