AB - New routes to the title compounds, involving improved conditions for the cyclopropanation, and a new method of constructing the central three‐carbon unit (based on the coupling of a Grignard reagent with an allylic acetate) give access to products for which the previously reported route was not satisfactory. For the new route, a synthesis of 5‐bromo‐2‐fluoro‐diphenyl ether was developed. Previously deduced relationships between structure and insecticidal activity apply for the new compounds: alkenes are generally more active than corresponding alkanes; substitution at the 3‐ or 4‐position (but not the 2‐) of the 1‐aryl group can enhance activity. In addition, some fluorine‐containing substituents lead to high activity.
