So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Jouffroy, Matthieu; Primer, David N.; Molander, Gary A. researched the compound: tert-Butyl 5-bromo-1H-indazole-1-carboxylate( cas:651780-02-8 ).Computed Properties of C12H13BrN2O2.They published the article 《Base-Free Photoredox/Nickel Dual-Catalytic Cross-Coupling of Ammonium Alkylsilicates》 about this compound( cas:651780-02-8 ) in Journal of the American Chemical Society. Keywords: photoredox nickel catalyzed coupling ammonium alkylsilicate hetero aryl bromide. We’ll tell you more about this compound (cas:651780-02-8).
Single-electron transmetalation is recognized as an enabling technol. for the mild transfer of alkyl groups to transition metal catalysts in cross-coupling reactions. Hypercoordinate silicates represent a new and improved class of radical precursors because of their low oxidation potentials and the innocuous byproducts generated upon oxidation Herein, authors report the cross-coupling of secondary and primary ammonium alkylsilicates with (hetero)aryl bromides in good to excellent yields. The base-free conditions have exceptional protic group tolerance on both partners, permitting the cross-coupling of unprotected primary and secondary amines.
From this literature《Base-Free Photoredox/Nickel Dual-Catalytic Cross-Coupling of Ammonium Alkylsilicates》,we know some information about this compound(651780-02-8)Computed Properties of C12H13BrN2O2, but this is not all information, there are many literatures related to this compound(651780-02-8).
