A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, COA of Formula: C11H8N2, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 244-63-3, Name is 9H-Pyrido[3,4-b]indole, molecular formula is C11H8N2. In a Article, authors is Li, Guijie，once mentioned of 244-63-3
A general and efficient synthesis of fluorenes or heterocycle-fused indenes including 3-thia-cyclopenta[a]indenes, 9-thia-indeno[1,2-a]indenes, 5,6-dihydroindeno[2,1-b]indoles has been developed. This methodology is realized by a multistep protocol involving first preparation of ortho-formylbiaryls through Suzuki-Miyaura coupling of o-bromobenzaldehydes with arylboronic acids or the coupling of aryl halides with 2-formylbenzene boronic acid, this is followed by Grignard addition and Friedel-Crafts cyclization reactions catalyzed by Br°nsted or Lewis acid to form the desired fluorene or indene rings. The method offers several advantages such as high yields, high selectivities, mild reaction conditions, easily accessible starting materials, and so on.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 244-63-3, help many people in the next few years.COA of Formula: C11H8N2
