A novel method for the preparation of acid-sensitive epoxides from olefins with the combined use of molecular oxygen and an aldoacetal catalyzed by a cobalt(II) complex was written by Yorozu, Kiyotaka;Takai, Toshihiro;Yamada, Tohru;Mukaiyama, Teruaki. And the article was included in Bulletin of the Chemical Society of Japan in 1994.Related Products of 15399-05-0 This article mentions the following:
An efficient synthesis of acid-sensitive epoxides, such as chromene oxide or the epoxide of an γ,δ-unsaturated alc., was successfully achieved by the oxygenation of olefins with the combined use of 1 atm of O2 and an aldehyde acetal catalyzed by a cobalt(II) complex containing a 1,3-diketone ligand. The reactions proceeded under mild and neutral conditions, and the desired epoxides were obtained in good yields. Neither overoxidn. nor decomposition of the epoxide was observed Furthermore, various silyl enol ethers and silyl ketene acetals, acid-sensitive compounds, were also smoothly monooxygenated to the corresponding α-hydroxy ketones and α-hydroxy carboxylic acid esters, resp. In the experiment, the researchers used many compounds, for example, Ethyl 2-hydroxy-3-phenylpropanoate (cas: 15399-05-0Related Products of 15399-05-0).
Ethyl 2-hydroxy-3-phenylpropanoate (cas: 15399-05-0) 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. 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.Related Products of 15399-05-0
