Alkylation of active methylene compounds with alcohols catalyzed by an iridium complex. [Erratum to document cited in CA147:322401] was written by Morita, Masao;Obora, Yasushi;Ishii, Yasutaka. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2007.Reference of 1190-39-2 This article mentions the following:
The authors accidentally missed citing two recent publications related to their work. The Reference 3(a) should read: “P. A. Slatford, M.K. Whittlesey and J.M.J. Williams, Tetrahedron Lett., 2006, 47, 6787.”. Reference 3(b) should read: “P.J. Black, G. Cami-Kobeci, M.G. Edwards, P.A. Slatford, M.K. Whittlesey and J.M.J. Williams, Organic Biomol. Chem., 2006, 4, 116.”. In the experiment, the researchers used many compounds, for example, malonic acid dibutyl ester (cas: 1190-39-2Reference of 1190-39-2).
malonic acid dibutyl ester (cas: 1190-39-2) 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. 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.Reference of 1190-39-2
