Silver-Catalyzed N-H Functionalization of Aryl/Aryl Diazoalkanes with Anilines
Herein, we report on the N-H functionalization reaction of primary and secondary anilines with diaryldiazoalkanes using simple AgPF6 as catalyst. We demonstrated broad applicability in the reaction of diaryldiazoalkanes with different anilines (31 examples, up to 97% yield). Furthermore, we propose a possible reaction mechanism for the N-H functionalization.

A chemoselective and scalable transfer hydrogenation of aryl imines by rapid continuous flow photoredox catalysis
The chemoselective reduction of diaryl imines in the presence of competitively reducible groups is uniquely accessed through precise control of reaction and irradiation time by continuous flow visible light photoredox catalysis. The method enables the mild and efficient transfer hydrogenation of diaryl imines in the presence of sensitive functionality including halides, ester, ketone, and cyano groups. The flow protocol is efficient, rapid (>98% conversion within 9 min) and readily scaled to deliver multigram quantities of amine products in high purity.

Iron-catalyzed C-C bond cleavage and C-N bond formation
A novel approach for C-N bond formation was developed by iron-catalyzed C-C bond cleavage. Anilines and sulfonamides reacted smoothly with 2-substituted 1,3-diphenylpropane-1,3-diones to afford N-alkylation products, in which the 1,3-dicarbonyl group acts as a leaving group in the presence of an iron catalyst. The reversible C-C bond cleavage plays a driving force to give the thermodynamically stable products. The method is complementary to the previous methods for C-N bond formation. Copyright
