Hatano, Kouta published the artcileSyntheses of 2,4-dicyanophenoxyacetic acid and its analogs, Category: nitriles-buliding-blocks, the main research area is cyanophenoxyacetate pesticide; phenoxyacetate cyano pesticide.
Cyanophenoxyacetic acids (I; R = H; R1 = H, CN; R2 = Me, H, CN) and their Et esters (I; R = Et) were prepared in order to test their pesticidal properties. E.g. Reimer-Tiemann reaction of o-HOC6H4CHO, followed by refluxing the resulting 2,4-(OHC)2C6H3OH with NH2OH.HCl in AcOH gave 2,4-(NC)2C6H3OH which reacted with BrCH2CO2Et to give I (R = Et, R1 = R2 = CN). The other I were prepared similarly.
Agricultural and Biological Chemistry published new progress about cyanophenoxyacetate pesticide; phenoxyacetate cyano pesticide. 34133-58-9 belongs to class nitriles-buliding-blocks, name is 4-Hydroxyisophthalonitrile, and the molecular formula is C8H4N2O, Category: nitriles-buliding-blocks.
