Methyl 2-thienylacetate (cas: 19432-68-9) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.SDS of cas: 19432-68-9

B(C6F5)3-catalyzed O-H insertion reactions of diazoalkanes with phosphinic acids was written by Zhang, Yangyang;Zhang, Xinzhi;Zhao, Jincheng;Jiang, Jun. And the article was included in Organic & Biomolecular Chemistry in 2021.SDS of cas: 19432-68-9 This article mentions the following:

A highly efficient base-, metal-, and oxidant-free catalytic O-H insertion reaction of diazoalkanes and phosphinic acids in the presence of B(C6F5)3 has been developed. This powerful methodol. provides a green approach towards the synthesis of a broad spectrum of α-phosphoryloxy carbonyl compounds with good to excellent yields (up to 99% yield). The protocol features the advantages of operational simplicity, high atom economy, practicality, easy scalability and environmental friendliness. In the experiment, the researchers used many compounds, for example, Methyl 2-thienylacetate (cas: 19432-68-9SDS of cas: 19432-68-9).
