A general and authoritative literature overview on Pd-catalyzed cross-dehydrogenative coupling reactions of (hetero)arenes from the origins to 2023, where not only the synthetic aspects were described but also the most relevant mechanistic features.
The selective synthesis of primary arylamines and diarylamines via coupling reactions with ammonia as a nitrogen source is still challenging.
Pd/NHC catalyzes the one-pot synthesis of diarylamine compounds from nitroarenes, by introducing triethylsilane as a reducing agent.
Porous activated carbon bearing OH and C
O groups, in the presence of a molecular oxidant, catalyzes metal-free cascade synthesis of diarylamines via enamine formation and oxidative aromatization.
A new catalytic antioxidation mechanism of diarylamines is proposed, highlighting a β-H transfer pathway via ROO˙ radicals, which shows that Fe(III) coordination significantly enhances radical-scavenging efficiency.
