AI Article Synopsis

  • Boracene-based alkylborate facilitates a new type of catalysis driven by visible light.
  • When excited, the borate compound can be easily oxidized by an excited iridium (Ir) photoredox catalyst.
  • Combining nickel (Ni) and Ir catalysts allows for efficient product formation even with low light intensity.

Article Abstract

Boracene-based alkylborate enabled visible light-mediated metallaphotoredox catalysis. The directly excited borate was easily oxidatively quenched by an excited Ir photoredox catalyst. Ni/Ir hybrid catalysis afforded the products under significantly low irradiance.

An efficient synthesis of a variety of 3-alkyl quinoxalinones via C-H direct alkylation by photoredox catalysis between quinoxalinones and alkylborates is reported. A range of quinoxalinones was tolerated well. This visible-light photocatalysis reaction allows access to structurally diverse 3-alkyl quinoxalinones in good to excellent yields.

Generation of Alkyl Radical through Direct Excitation of Boracene-Based Alkylborate.

J Am Chem Soc

June 2020

Division of Pharmaceutical Sciences, Graduate School of Medical Sciences, Kanazawa University, Kakuma-machi, Kanazawa 920-1192, Japan.

The generation of tertiary, secondary, and primary alkyl radicals has been achieved by the direct visible-light excitation of a boracene-based alkylborate. This system is based on the photophysical properties of the organoboron molecule. The protocol is applicable to decyanoalkylation, Giese addition, and nickel-catalyzed carbon-carbon bond formations such as alkyl-aryl cross-coupling or vicinal alkylarylation of alkenes, enabling the introduction of various C(sp) fragments to organic molecules.
