New discoveries in chemical research and development in 2021. name: 1-Phenyl-1,2,3,4-tetrahydroisoquinoline, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 22990-19-8, Name is 1-Phenyl-1,2,3,4-tetrahydroisoquinoline, molecular formula is C15H15N. In a Patent，once mentioned of 22990-19-8
A kind of catalytic palladium 1-substituted -1, 2, 3, 4-isoquinoline compound selective partial dehydrogenation synthesis of 1-substituted -3,4-dihydro-quinoline method. Reaction temperature: 0-80C. For simple and easily obtained cyclic amine compound such as tetrahydroisoquinoline compound, can be obtained through selective dehydrogenation of the corresponding imine compound, its conversion rate is up to 99%, and part of the dehydrogenation product with the totally dehydrogenation product proportion is more than 20:1. The operation of the invention is simple and convenient and practical and easy, cheap and easily obtained raw materials and catalyst, mild reaction conditions, the catalyst can be recycled, the actual cost is greatly reduced. Furthermore, direct dehydrogenation the synthesis of tetrahydroisoquinolines 3,4-dihydro-quinoline method, with atom economy, the friendly advantage of the environment. (by machine translation)
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 22990-19-8, help many people in the next few years.name: 1-Phenyl-1,2,3,4-tetrahydroisoquinoline
