H-β zeolite, an efficient reusable catalyst for one-pot synthesis of isatins from anilines was written by Raj, I. Victor Paul;Shaikh, Tanveer Mahamadali;Sudalai, Arumugam. And the article was included in Acta Chimica Slovenica in 2010.Recommanded Product: 150560-58-0 This article mentions the following:
The authors described a simple and highly efficient procedure for the single-step preparation of isatins from the com. available anilines using H-β zeolite as a truly heterogeneous catalyst. H-β zeolite is readily separated from the reaction mixture by simple filtration and was reused several times without considerable loss of activity. In the experiment, the researchers used many compounds, for example, 5-Isopropylindoline-2,3-dione (cas: 150560-58-0Recommanded Product: 150560-58-0).
5-Isopropylindoline-2,3-dione (cas: 150560-58-0) belongs to indole derivatives. In addition to tryptophan, indigo, and indoleacetic acid, numerous compounds obtainable from plant or animal sources contain the indole molecular structure. In addition to indole, the strain-release chemistry worked for numerous substrates including amines, alcohols, thiols, carboxylic acids, imidazoles, and pyrazoles.Recommanded Product: 150560-58-0
