《Aromatic nucleophilic substitution. XIV. Kinetics of reactions of methyl and ethyl esters of pentafluorobenzoic acid with sodium alkoxides》 was written by Kobrina, L. S.; Furin, G. G.; Kollegov, V. F.; Chertok, V. S.; Yakobson, G. G.. COA of Formula: C9H5F5O2 And the article was included in Izvestiya Sibirskogo Otdeleniya Akademii Nauk SSSR, Seriya Khimicheskikh Nauk in 1972. The article conveys some information:
Nucleophilic substitution of C6F5CO2R (R = Me, Et) by the corresponding NaOR in ROH-Et2O, MeOH-dioxane, and MeOH-C6H6 was 1st order in each reagent. The rate of ortho substitution decreased more sharply with increasing alc. content of the solvent than that of the para substitution; however, the rate of para substitution in MeOH-C6H6 increased with the solvent polarity. In the experimental materials used by the author, we found Ethyl 2,3,4,5,6-pentafluorobenzoate(cas: 4522-93-4COA of Formula: C9H5F5O2)
Ethyl 2,3,4,5,6-pentafluorobenzoate(cas: 4522-93-4) belongs to esters. Esters are more polar than ethers but less polar than alcohols. COA of Formula: C9H5F5O2 They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.
