New discoveries in chemical research and development in 2021. Application In Synthesis of 2-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. 3340-78-1, Name is 2-Phenyl-1,2,3,4-tetrahydroisoquinoline, molecular formula is C15H15N. In a Article，once mentioned of 3340-78-1
With visible-light irradiation, a mild, simple, and efficient metal-free photocatalytic system for the facile construction of sp3-sp 3 C-C bonds between tertiary amines and activated C-H bonds has been achieved. Spectroscopic study and product analysis demonstrate for the first time that photoinduced electron transfer from N-aryl tetrahydroisoquinolines to eosin Y bis(tetrabutylammonium salt) (TBA-eosin Y) takes place to generate TBA-eosin Y radical anion, which can subsequently react with nucleophiles and molecular oxygen. More strikingly, electron spin resonance (ESR) measurements provide direct evidence for the formation of superoxide radical anions (O 2) rather than singlet oxygen (1O 2) during visible-light irradiation. This active species is therefore believed to be responsible for the large rate of acceleration of the aerobic photocatalytic reactions. Light work: With visible-light irradiation (lambda>450 nm), a mild, simple and efficient metal-free photocatalytic system for the facile construction of sp3-sp3 C-C bonds between tertiary amines and activated C-H bonds has been achieved (see scheme). Electron spin resonance measurements offer direct evidence for the formation of superoxide radical anions (O2) during visible-light irradiation. Copyright
