Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition, 154445-78-0, Name is 2,2,4,6,7-Pentamethyl-2,3-dihydrobenzofuran-5-sulfonyl chloride, SMILES is O=S(C1=C(C)C(C)=C(OC(C)(C)C2)C2=C1C)(Cl)=O, in an article , author is Mitra, Shubhanjan, once mentioned of 154445-78-0, Name: 2,2,4,6,7-Pentamethyl-2,3-dihydrobenzofuran-5-sulfonyl chloride.
Copper(I)-Catalyzed Oxidative Coupling between 2-Aminobenzothiazole and Terminal Alkyne: Formation of Benzothiazine
An unprecedented formation of benzothiazine during copper(I)-catalyzed oxidative coupling of 2-aminobenzothiazole and terminal alkyne in air has been observed. This unique transformation possibly occurs through the ring opening of 2-aminobenzothiazole and subsequent oxidative coupling with alkyne followed by intramolecular cyclization. A variety of substituted benzo[b][1,4]thiazine-4-carbonitriles are obtained by this protocol.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 154445-78-0, you can contact me at any time and look forward to more communication. Name: 2,2,4,6,7-Pentamethyl-2,3-dihydrobenzofuran-5-sulfonyl chloride.
