Cationic Rh(I) Catalyst in Fluorinated Alcohol: Mild Intramolecular Cycloaddition Reactions of Ester-Tethered Unsaturated Compounds was written by Saito, Akio;Ono, Takamitsu;Hanzawa, Yuji. And the article was included in Journal of Organic Chemistry in 2006.Name: 5-Methylisobenzofuran-1(3H)-one This article mentions the following:
In fluorinated alcs., the cationic Rh(I) species, which is derived from [Rh(COD)Cl]2 and AgSbF6, efficiently catalyzed intramol. [4+2] cycloaddition reactions of ester-tethered 1,3-diene-8-yne derivatives The catalytic system was also effective in intramol. [5+2] cycloaddition reactions of ester-tethered ω-alkynyl vinylcyclopropane compounds In the experiment, the researchers used many compounds, for example, 5-Methylisobenzofuran-1(3H)-one (cas: 54120-64-8Name: 5-Methylisobenzofuran-1(3H)-one).
5-Methylisobenzofuran-1(3H)-one (cas: 54120-64-8) belongs to benzofurans derivatives. Benzofuran derivatives have shown many biological activities, including antifungal and antimicrobial properties, and acting as antagonists of H3 receptors and angiotensin II. Benzofurans are stable towards alkali and readily polymerize on treatment with sulfuric acid, due to which they are useful for the preparation of low cost chemically relatively inert resins.Name: 5-Methylisobenzofuran-1(3H)-one
