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.

Unified Protocol for Cobalt-Catalyzed Oxidative Assembly of Two Aryl Metal Reagents Using Oxygen as an Oxidant

The first cobalt-catalyzed oxidative cross-coupling reaction of two aryl metal reagents is described. An equivalent amount of two aryl Grignard or lithium reagents, after mediation by an equivalent amount of simple ClTi(OEt)3, was facilely assembled under the catalysis of 1 mol % of CoCl2/10 mol % of DMPU using oxygen. The cross-couplings between various aryl metal reagents, especially between two structurally similar aryl Grignard reagents, proceeded smoothly and selectively and, thus, provided a highly general and efficient method for the construction of biaryl compounds.

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.

Iron-catalyzed C-H and C-C bond cleavage: A direct approach to amides from simple hydrocarbons

Something functional: The title reaction proceeds in the presence of azide and water to deliver amides in high yields, and it can be used in a ring-expansion strategy to generate lactams. A mechanism is proposed based on experimental results. This reaction offers a new approach to functionalizing simple and readily available hydrocarbons.

Structures and excited states of extended and folded mono-, di-, and tri-N-arylbenzamides

The relationship between molecular structure and electronic properties of 18 N-arylbenzamides has been investigated. The secondary amides adopt extended trans-amide conformations, whereas the tertiary amides adopt folded cis-amide conformations in which the N-aryl group is approximately perpendicular to the benzoyl group. The N-aryl groups of the tertiary di- and triamides occupy the same face of the benzoyl group and display edge-to-face aryl-aryl interactions. The long-wavelength absorption maxima of the secondary amides are red-shifted as the number of N-aryl groups increases, whereas the tertiary amides display are blue-shifted. ZINDO calculations aid in the assignment of the absorption and luminescence spectra. In all cases the lowest energy singlet state is assigned to a forbidden n,B* (carbonyl lone-pair to benzoyl) transition. The structureless fluorescence of the secondary and tertiary amides is assigned to planar and twisted n.B* singlets, respectively. The allowed absorption bands are assigned to A,B* (arene-to-benzoyl) or A,A* (arene-to-arene) transitions which are localized on a single arene, and the structured phosphorescence is assigned to A,A* triplet states.
