In contrast to the recent breakthrough in electrochemical C–H aminations, the electrochemicallyoxidative C–N bondformation through a C–C bond cleavage is rarely studied. This work describes an electrochemical C–C amination of alkylarenes for the efficient synthesis of versatile anilines, as well as carbonyl compounds. With the cheap and durable graphite plates as electrodes, and in a simple undivided

development of efficient and selective C-N bond-forming reactions from abundant feedstock chemicals remains a central theme in organic chemistry owing to the key roles of amines in synthesis, drug discovery, and materials science. Herein, we present a dual catalyticsystem for the N-alkylation of diverse aromatic carbocyclic and heterocyclic amines directly with carboxylicacids, by-passing their preactivation

A hydrogen-bond-catalyzed direct reductive amination of aldehydes is reported. The acid- and metal-free process uses thiourea as organocatalyst and the Hantzsch ester for transfer-hydrogenation and allows for the high-yielding synthesis of diverse amines.
An efficient and modular one-pot synthesis of polysubstituted aromatic amines by a mild reductive amination procedure is described and the biological potential of these nitrogen-centered compounds is demonstrated by growth inhibition of murine connective tissue cells and microscopy-based morphological studies.

isothiouronium chloride as a recoverableorganocatalyst for the activation of the imine intermediate through hydrogen bonding is described. A mild and operationally simple fragment coupling procedure was accomplished with a wide range of aldehydes as well as amines in good to excellent yields. In addition, the S-benzyl isothiouronium chloride catalyst was easily recovered by simple filtration and reused
