| Abstract: | A series of triorganotin chrysanthemumates (2,2‐dimethyl‐3‐(2‐methyl‐1‐propenyl)cyclopropanecarboxylates) (R3SnO2CC9H15) where R = methyl, ethyl, n‐butyl and phenyl was synthesized. The solid state structures were deduced using infrared (IR) and Mössbauer spectroscopies. The spectroscopic results indicated that all the compounds were found to be five‐coordinated in the solid state. Based on the NMR results, all the compounds are tetrahedral in solution. Larvicidal activities of the compounds were evaluated against the second instar stage of Aedes aegypti, Anopheles stephensi and Culex pipiens quinquefasciatus mosquitoes. The toxicity results indicated that these compounds of triorganotins were effective larvicides against all three species of larvae. Copyright © 2011 John Wiley & Sons, Ltd. |
