Cu(OTf)2-Mediated Cross-Coupling of Nitriles and N-Heterocycles with Arylboronic Acids to Generate Nitrilium and Pyridinium Products**

Metal-catalyzed C–N cross-coupling generally forms C?N bonds by reductive elimination from metal complexes bearing covalent C- and N-ligands. We have identified a Cu-mediated C–N cross-coupling that uses a dative N-ligand in the bond-forming event, which, in contrast to conventional methods, generates reactive cationic products. Mechanistic studies suggest the process operates via transmetalation of an aryl organoboron to a CuII complex bearing neutral N-ligands, such as nitriles or N-heterocycles. Subsequent generation of a putative CuIII complex enables the oxidative C–N coupling to take place, delivering nitrilium intermediates and pyridinium products. The reaction is general for a range of N(sp) and N(sp2) precursors and can be applied to drug synthesis and late-stage N-arylation, and the limitations in the methodology are mechanistically evidenced.

A soluble copper(I) source and stable salts of volatile ligands for copper-catalyzed C-X couplings

A stable adduct of CuI with Bu4NI, soluble in organic solvents, has been identified as an effective catalyst for copper-catalyzed C-N and C-O couplings. In addition, stable nonhygroscopic salts of some high performance ligands (diamine MsOH salts/CuX and copper(II) diketonates) were shown to be of similar and sometimes greater reactivity compared to the literature reagents for these couplings. Furthermore, these more robust conditions result in more reproducible results.
