Recommanded Product: 1-Bromo-2-pentyne. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 1-Bromo-2-pentyne, is researched, Molecular C5H7Br, CAS is 16400-32-1, about One-Pot Oxidative C-H Activation/Aza-Prins-Type Reaction of Tertiary Alkynylamines: A Counter Ion-Induced Iminium Ion-Alkyne Cyclization. Author is Orejarena Pacheco, Julio Cesar; Pusch, Stefan; Geske, Leander; Opatz, Till.
Herein, the design and development of a new one-pot and metal-free oxidative C-H activation/aza-Prins type cyclization of alkynylamines was reported. The scope of this method was demonstrated by the preparation of ten new pyrido[2,1-a]isoquinolines I [R1 = R2 = H, OMe; R3 = H, Ph, 2-thienyl, etc.; R4 = H, Et; stereo = cis, trans] in moderate to high yields (38-92%). Furthermore, a mechanistic proposal for the alkyne aza-Prins cyclization was described based on DFT calculations
In some applications, this compound(16400-32-1)Recommanded Product: 1-Bromo-2-pentyne is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
