And the article was included in Organic Letters in 2008.Formula: C11H9F3O3 The following contents are mentioned in the article:
On page 3915, we overlooked previous work by Sasaki et. al. which discusses the enantioselective synthesis of tertiary alcs. via addition of diethylzinc to trifluoromethyl ketones in the presence of nitrogen-containing polydentate ligands. The following reference citation should be included: “Higashiyama, K.; Sasaki, S.; Kubo, H.; Yamauchi, T.; Ishii, A.; Kanai, M. Japanese Patent 200609692, Apr. 13, 2006.”. This study involved multiple reactions and reactants, such as Ethyl 4-(2,2,2-Trifluoroacetyl)benzoate (cas: 898787-14-9Formula: C11H9F3O3).
Ethyl 4-(2,2,2-Trifluoroacetyl)benzoate (cas: 898787-14-9) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Formula: C11H9F3O3
