The title complex, obtained by co-crystallization of its molecular components from methanol, was characterized by low-temperature X-ray diffraction. The crystal structure (triclinic, space group P1, Z = 2) consists of two monomeric and crystallographicall

A microwave-assisted N-fluorobenzenesulfonimide (NFSI)/Lewis acid-catalyzed Beckmann rearrangement was developed. The remarkable promotion to the electrophilicity of NFSI by Lewis acids was illustrated utilizing a series of readily available oxime substrates. The action model between NFSI and Lewis acids was probed by control experiments and theoretical calculations.

A nickel-catalyzed approach for the synthesis of biaryl compounds from N,N-disulfonylmethylamines and arylboronic acids has been developed. Instead of arenesulfonyl chlorides, various N,N-disulfonylmethylamines were used as the aryl source through extrusion of SO2 to give cross-coupling products in moderate to good yields. A NiCl2(dppp)-catalyzed [dppp = 1,3-bis(diphenylphosphino)propane] desulfitative Suzuki-Miyaura cross-coupling reaction between N,N-disulfonylmethylamines and arylboronic acids is described for the first time. The biaryl compounds are obtained in moderate to good yields.

Reaction of N,N-dimethylaniline, N,N-dimethylnaphthalen-1-amine and 1,8-bis(dimethylamino)- naphthalene (proton sponge) with 1-chloromethyl-4- fluorodiazonia-bicyclo[2.2.2]octane bis(tetrafluoroborate) (Selectfluor) and N-fluorobenzenesulfonimide (NFSI) h

Oxidation of a series of defined palladium(II) complexes bearing a bidentate ligand, and a methyl and an amidato substituent was carried out with the aim to gain a better understanding of the inherent requirements for C-N bond-formation from Pd complexes in high oxidation state. This work clarified the role of the individual nitrogen sources and has important implication for alkyl-nitrogen bond-forming reactions catalyzed by Pd. Copyright
Steric crowding makes challenging Csp3 - F reductive eliminations feasible

A high-yielding fluorination of (triphos)Pt-R+ has been achieved using an array of F+ sources, with XeF2 yielding R-F in minutes. The C-F coupling proved to be a stereoretentive process that proceeds via a concerted reductive elimination from a putative dicationic Pt(IV) center. The larger the steric congestion of the (triphos)Pt-Csp3+ complexes, the more efficient the fluorination, seemingly a result of sterically accelerated C-F reductive elimination along with simultaneous deceleration of its competing processes (β-H elimination).
