Synthesis of diversely functionalized symmetrical benzidines through electrochemical dehydrogenative cross-couplingreaction of two N,N-disubstituted anilines, is described. The reactions conducted under mild conditions with no oxidizing reagents and transition metal catalysts.
the established 2D PbI2 semiconductor through a mild solution method yielded the first leadiodide superlattice, EtDAB⋅4PbI2 (EtDAB=tetraethylbenzidine), with radical and non‐radical forms. The non‐radical form has a non‐ionic structure that differs from the common ionic structures for inorganic–organic hybrid lead halides. The radical form shows five orders of magnitude greater conductance and broader

The oxidativecoupling to 4,4'-N,N,N',N'-tetraalkylbenzidines is the main reaction observed during a study on the reactivity of N,N-dialkylanilines with SbCl 5. A possible reaction mechanism is presented and discussed in comparison with the N,N-dialkylanilines oxidativecoupling achieved with other Lewis acids.
