electrochemical C-H aminations of arenes at room temperature using undivided electrochemical cells, thereby providing a practical solution for the construction of arylamines. The use of n-Bu4NI as a redox mediator is crucial for this transformation. On the basis of mechanistic studies including kinetic profiles, isotope effects, cyclic voltammetric analyses, and radical inhibition experiments, the reaction appears
The preparation and X‐ray structural characterization of aliphatic amino iodane (III) reagents has been realized. These new reagents could be used for the Cu‐catalyzed directed electrophilic amination of aryl amines.

Bis(N-picolinamide)cobalt(II) complexes containing trans isothiocyanate ligands are reported to have significantly enhanced activity toward fungal species, when compared the cis complexes. They display >80 % growth inhibition of fungal strains and no reported toxicity toward bacterial species or mammalian cells.
