| Ethyl chrysanthemumate Usage And Synthesis |
| Chemical Properties | clear colorless to yellow liquid | | Uses | Ethyl Chrysanthemate is an organic building block used in the synthesis of various chemical compounds, such as insecticide, Resmethrin (R144685). It is used in the preparation of trans-norchrysanthemates and trans-norpyrethrates, having insecticidal activity. | | Synthesis Reference(s) | Tetrahedron Letters, 22, p. 1783, 1981 DOI: 10.1016/S0040-4039(01)90438-1Synthesis, p. 600, 1976 DOI: 10.1055/s-1976-24132 | | Purification Methods | Purify the ester by vacuum distillation. The free trans-acid has m 54o (from EtOAc), and the free cis-acid has m 113-116o (from EtOAc). The 4-nitrophenyl ester has m 44-45o (from pet ether) [Campbell & Harper J Chem Soc 283 1945, IR: Allen et al. J Org Chem 22 1291 1957]. [Beilstein 9 II 45.] |
