Reticular framework materials thrive on designability, but unexpected reaction outcomes are crucial in exploring new structures and functionalities. By combining "incompatible"building blocks, we employed geometric frustration in reticular materials leadi

Herein, theN-arylation of aromatic heterocycles like indoles and pyrroles is reported by a Pd nanocatalyst under ligand- and Cu-free conditions. The reaction conditions tolerate several functional groups and work very efficiently for aryl iodides and bromides. Aryl chlorides are also successful as the coupling partners albeit with lower yields. The methodology is also applicable for theN-arylation of aliphatic primary amines as demonstrated by the reactions of benzylamine with several aryl iodides as well as bromides. The recyclable Pd nanocatalyst catalyzes the reaction by a heterogeneous mechanism, which has been demonstrated by several techniques including the three phase test and thein situICP-MS analysis of the reaction mixture.

A metal-free convergent paired electrolysis strategy to synthesize benzylic amines through direct arylation of tertiary amines and benzonitrile derivatives at room temperature has been developed. This TEMPO-mediated electrocatalytic reaction makes full use of both anodic oxidation and cathodic reduction without metals or stoichiometric oxidants, thus showing great potential and advantages for practical synthesis. This convergent paired electrolysis method provides a straightforward and powerful means to activate C?H bonds and realize cross-coupling with cathodically generated species.
