On February 4, 2022, Matsumoto, Akira; Yamamoto, Masanori; Maruoka, Keiji published an article.Formula: C13H11Br The title of the article was Cationic DABCO-Based Catalyst for Site-Selective C-H Alkylation via Photoinduced Hydrogen-Atom Transfer. And the article contained the following:
A series of hydrogen-atom transfer (HAT) catalysts based on the readily available and tunable 1,4-diazabicyclo[2.2.2]octane (DABCO) structure was designed, and their photoinduced HAT catalysis ability was demonstrated. The combination of HAT catalyst with an acridinium-based organophotoredox catalyst enabled efficient and site-selective C-H alkylation of substrates ranging from unactivated hydrocarbons to complex mols. Notably, a HAT catalyst with addnl. substituents adjacent to a nitrogen atom further improved the site selectivity. Mechanistic studies suggested that the N-substituent of the catalyst played a crucial role, assisting in the generation of a dicationic aminium radical as an active species for the HAT process. The experimental process involved the reaction of 4-(Bromomethyl)-1,1′-biphenyl(cas: 2567-29-5).Formula: C13H11Br
