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 fo

The insecticidal activities against houseflies (Musca domestica L.) and mustard beetles (Phaedon cochleariae Fab.) of 29 new 5-benzyl-3-furylmethyl 2,2-dimethyl-cyclopropane-carboxylates are compared with those of the corresponding chrysanthe-mate (b

Following the discovery of insecticidal activity in (2E,4E)-N-(2-methylpropyl)-6-phenylhexa-2,4-dienamide, structural analogues containing variations of the central pentadiene system have been examined. They include the five compounds with extra meth

Relative potencies for 20 pyrethroids against the Mediterranean flour moth Ephestia kuhniella, and its hymenopterous parasite Venturia canescens, show a wide range of selectivity factors (2-140), indicating the possibility of identifying compounds wi

The phosphorothionate insecticide diazinon was incubated with liver microsomes from the sheep, cow, pig, guinea-pig, rat, turkey, chicken and duck. Metabolism by liver slices of most of these species was also examined. Hydroxydiazinon, isohydroxydiaz

Preparation of 3-phenoxybenzyl chrysanthemates and their dihalovinyl analogues substituted with a cyano group at the 2-, 6-, (R)-α-, or (S)-α- positions is described. The (R)- and (S)- isomers of α-cyano-3-phenoxybenzyl esters of 2,2-difluoro-, -d

A report by Staudinger and Ruzicka of the insecticidal activity of an ester of pulegenic acid with mixed naturally derived alcohols had not been examined further, and had been misinterpreted in a review. Therefore, two isomeric pulegenic and nine rel

The more stable synthetic pyrethroids, the main subject of this review, are based on the earlier natural and synthetic pyrethroids, but differ so markedly from them in properties and activity as to constitute a new class of insecticides. The value of

Esters of 2,2-dimethyl-3-(2,2-dichlorovinyl)-cyclopropanecarboxylic acid with appropriate alcohols are more active insecticides than the corresponding 3-isobutenyl compounds (chrysanthemates). (±)-Cis and (±)-trans forms of the dichloro acid are ob

The influence of the nature, number and relative dispositions of substituents on the furan ring of furfuryl and 3-furylmethy chrysanthemates on insecticidal activity to two insect species is described. 5-Benzyl-3-furylmethyl chrysanthemate was the mo
