WebJun 23, 2016 · To investigate the role of the photocatalyst in switching on nickel-catalyzed aryl amination, we used Ni (cod) 2. In the absence of light, the formation of aniline 10 was severely diminished (10% yield), whereas standard reaction conditions yielded 10 in 91% yield. This result supports our hypothesis that the cross-coupling is light-mediated ... WebApr 7, 2024 · The above are all Pd‐NHCs catalyzed Suzuki‐Miyaura and Buchwald‐Hartwig cross‐coupling of amides by selective C−N(O) cleavage with η 3 ‐allyl‐Pd coordination mode. These catalysts were used to catalyze amide C−N bonds cleavage for the first time, opening a new chapter in amide activation.
