We have developed an efficient manganese-catalyzed amidation of various heteroarenes via C?H bond activation using readily available sulfonyl azides. The key step is heteroarene directed electrophilic aromatic metalation using MnBr(CO)5 as catalyst. This method offers excellent chemical yields and regioselectivity with good functional group tolerance. This base metal catalyzed reaction proceeds efficiently using water as the only solvent and nitrogen is the only byproduct. (Figure presented.).

Rh(III)-catalyzed intermolecular direct aromatic C-H bond amidation with amides has been accomplished under mild reaction conditions. This protocol is applicable to a broad range of N-chelator-containing arenes amidated with aromatic and aliphatic sulfonamides. A possible mechanism is proposed according to the experimental results.

The first systematic mechanism study of C-F reductive elimination from a transition metal complex is described. C-F bond formation from three different Pd(IV) fluoride complexes was mechanistically evaluated. The experimental data suggest that reductive elimination occurs from cationic Pd(IV) fluoride complexes via a dissociative mechanism. The ancillary pyridyl-sulfonamide ligand plays a crucial role for C-F reductive elimination, likely due to a K 3 coordination mode, in which an oxygen atom of the sulfonyl group coordinates to Pd. The pyridyl-sulfonamide can support Pd(IV) and has the appropriate geometry and electronic structure to induce reductive elimination.
