SYNTHESIS OF SPIROCYCLOPROPANEINDENE PYRETHROIDS

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.

Insecticidal pyrethroid compositions

This invention relates to novel insecticidal compositions comprising a m-phenoxybenzyl ester of a spirocarboxylic acid and an insecticidal agent of chlorinated camphene; 0,0-dimethyl-0-p-nitrophenyl phosphorothioate; N'-(4-chloro-o-tolyl)-N,N-dimethylformamidine; 2-(diethoxy-phosphinylimino)-4-methyl-1,3-dithiolane; 0,0-dimethyl-S-[4-oxo-1,2,3-benzotriazin-3-(4H)-ylmethyl]phosphorodithioate; 1-naphthyl N-methylcarbamate, 0,0-dimethylphosphorodithioate of diethylmercaptosuccinate; or mixtures of the latter named chemical insecticidal agents and to the use of the above compositions for protecting agricultural crops from attack by insect pests.
