Reported here is the redox neutral electrochem. C(sp2)-C(sp3) cross-coupling reaction of bench-stable aryl halides or β-bromostyrene (electrophiles) and benzylic trifluoroborates (nucleophiles) using nonprecious, bench-stable NiCl2·glyme/polypyridine catalysts in an undivided cell configuration under ambient conditions. The broad reaction scope and good yields of the Ni-catalyzed electrochem. coupling reactions were confirmed by 50 examples of aryl/β-styrenyl chloride/bromide and benzylic trifluoroborates. Potential applications were demonstrated by electrosynthesis and late-stage functionalization of pharmaceuticals and natural amino acid modification, and three reactions were run on gram-scale in a flow-cell electrolyzer. The electrochem. C-C cross-coupling reactions proceed through an unconventional radical transmetalation mechanism. This method is highly productive and expected to find wide-spread applications in organic synthesis.

The first adducts of NHCs (= N-heterocyclic carbenes) with aromatic polyphosphorus complexes are reported. The reactions of [Cp*Fe(η5-P5)] (1) (Cp* = pentamethyl-cyclopentadienyl) with IMe (= 1,3,4,5-tetramethylimidazolin-2-ylidene), IMes (= 1,3-bis(2,4,6-trimethylphenyl)-imidazolin-2-ylidene) and IDipp (= 1,3-bis(2,6-diisopropylphenyl)-imidazolin-2-ylidene) led to the corresponding neutral adducts which can be isolated in the solid state. However, in solution, they quickly undergo a dissociative equilibrium between the adduct and 1 including the corresponding NHC. The equilibrium is influenced by the bulkiness of the NHC. [Cp”Ta(CO)2(η4-P4)] (Cp” = 1,3-di-tert-butylcyclopentadienyl) reacts with IMe under P atom abstraction to give an unprecedented cyclo-P3-containing anionic tantalum complex. DFT calculations shed light onto the energetics of the reaction pathways.

Pt···Pt and π-π interactions were developed by using N-deprotonated α-carboline as a bridging ligand. The complexes in doped thin films exhibit efficient red to NIR emission from short-lived (τ = 0.9-2.1 μs) triplet metal-metal-to-ligand charge transfer (3MMLCT) excited states. Red OLEDs demonstrate high maximum external quantum efficiencies (EQEs) of ≤23.3% among the best PtII-complex-doped devices. The maximum EQE of 15.0% and radiance of 285 W sr-1 m-2 for NIR OLEDs (λEL = 725 nm) are unprecedented for devices based on discrete mol. emitters. Both red and NIR devices show very small efficiency roll-off at high brightness. Appealing operational lifetimes also were revealed for the devices.

Author is Bandini, Marco; Bernardi, Fernando; Bottoni, Andrea; Cozzi, Pier Giorgio; Miscione, Gian Pietro; Umani-Ronchi, Achille.

A combined exptl. and theor. investigation has been carried out on a new catalytic system, based on bis(oxazoline) (BOX) complexes of titanium. These catalytic species are able to reduce aromatic ketones with good enantiomeric excesses and satisfactory yields. The exptl. and the computational (DFT) evidence has provided useful information on the nature of the active catalytic species and on the mechanism of the reaction. The most likely reaction path involves a TiIV catalytic species. This result agrees with exptl. obtained evidence that seems to rule out the presence of TiIII species. The anal. of the structure of the transition state corresponding to the reduction process (the addition of the hydride to the carbonyl system), provides an interesting insight on the enantioselectivity that characterizes this reaction.
