Visible-Light-Promoted Aerobic Oxyphosphorylation of α-Diazoesters with H-Phosphine Oxides was written by Zhou, Hongyan;Wang, Ganggang;Wang, Cunhui;Yang, Jingya. And the article was included in Organic Letters in 2022.COA of Formula: C7H8O2S This article mentions the following:
A visible-light-promoted aerobic oxyphosphorylation of α-diazoesters and H-phosphine oxides was developed. Using air as the O source, the reaction proceeded smoothly at room temperature under blue-light irradiation The α-diazoesters, O2, and H-phosphine oxides are conveniently incorporated into a C-O-P(O) unit in one step. The preliminary mechanistic studies indicated that a light-triggered radical process is involved. The developed strategy shows the unrevealed reactivity of diazo compounds with H-phosphine oxides and has potential value in synthetic applications. In the experiment, the researchers used many compounds, for example, Methyl 2-thienylacetate (cas: 19432-68-9COA of Formula: C7H8O2S).
Methyl 2-thienylacetate (cas: 19432-68-9) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. 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.COA of Formula: C7H8O2S
