Research speed reading in 2021. An article , which mentions Electric Literature of 3340-78-1, molecular formula is C15H15N. The compound – 2-Phenyl-1,2,3,4-tetrahydroisoquinoline played an important role in people’s production and life., Electric Literature of 3340-78-1
The oxidation of N-phenyltetrahydroisoquinolines occurs rapidly with DDQ. Under ambient conditions and in the presence of nitromethane, the corresponding beta-nitroamine derivatives are isolated in good to excellent yields. Variation in the electronic nature of the isoquinoline and the N-phenyl substituent showed that a broad range of substituents are tolerated, with electronic communication between the isoquinoline aromatic ring and the C1 carbon being stronger than with the N-aryl ring. Reduction of the beta-nitroamines to the corresponding novel chiral vicinal diamines are straightforward. Examination of the reaction by 1H NMR spectroscopy suggested that the reaction proceeds via an iminium ion, which then reacts with nitromethane upon work-up. This information was used to shorten the required reaction time.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 3340-78-1 is helpful to your research. Electric Literature of 3340-78-1
