A series of alkyl-substituted pyrethroid analogs were synthesized from ethyl 3,3-dialkyl-3'-alkylspiro-2-carboxylates.Cyclopropanation of acetyl- and methoxycarbonylbenzofluvenes, obtained from 1H-indene, by sulfur ylides containing a fragment of the pyrethroid alcohol component, led to compounds not exhibiting insecticidal activity.

This is a novel process for the preparation of m-phenoxybenzaldehyde, a useful and valuable intermediate for the synthesis of pyrethroid type pesticides. The process comprises halogenation of m-phenoxytoluene on the side chain, in an inert solvent and in the presence of free radical initiators or strong light to a mixture of the corresponding mono and dihalo derivatives, and conversion of the mixture to m-phenoxybenzaldehyde by a Sommelet-type reaction.
