STUDIES ON CHRYSANTHEMATE DERIVATIVES .3. SYNTHESIS AND INSECTICIDAL ACTIVITY OF 1-INDANYL AND 2-INDANYL CHRYSANTHEMATES

Indanyl 1-and 2-alcohols have been found to be a new entry in the list of “active alcohols” as the alcohol part of pyrethroids. Various substituted indanyl chrysanthernates were prepared and their insecticidal activity was tested on American cockroachs. These esters generally showed the substantial insecticidal activity, in which 4-allyl-1-indanyl ester 20c was more potent than allethrin. Examination of substituents on 1-indanyl esters afforded some interesting results that methyl and allyl groups on the 4-position of the indanol nucleus were excellent and that no obvious electronic effects were observed. © 1978 Taylor & Francis Group, LLC.
