Methyl 2-thienylacetate (cas: 19432-68-9) 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. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Name: Methyl 2-thienylacetate

Rhodium catalyzed reaction of formylbenzoyldiazomethane with thiophene derivatives was written by Kim, Hong-Seok;Kim, Sang Hwa;Kim, Dong Il. And the article was included in Journal of the Korean Chemical Society in 1996.Name: Methyl 2-thienylacetate This article mentions the following:

The title reactions, catalyzed by Rh2(OAc)4, gave thienyl-substituted oxo aldehydes I (R1 = H, Me, Br, CH2COOMe; R2 = H, Me, Cl) or ylides such as II. In the experiment, the researchers used many compounds, for example, Methyl 2-thienylacetate (cas: 19432-68-9Name: Methyl 2-thienylacetate).
