A series of new rhodium (I) complexes supported by bidentate nitrogen-donor ligands with varying electronic and steric properties were synthesized in situ and evaluated for catalytic arene C–H/D activation. In trifluoroacetic acid (HTFA), these complexes are proposed to mediate H/D exchange of arene C–H/D bonds by an electrophilic aromatic substitution mechanism that involves Rh-mediated activation of HTFA (or DTFA). DFT calculations support the proposed pathway for the H/D exchange reactions.

A simple and convenient method for the synthesis of 1,4-diazabutadienes (=N,N′-ethane-1,2-diylidenebis[amines]) by grinding glyoxal (=ethanedial) or an α-diketone and anilines (=benzenamines) in the presence of TsOH in a mortar with a pestle is described.
