The mechanism of a recently reported Suzuki coupling reaction of quinoline-derived allylic N,O-acetals has been studied using a combination of structural, stereochemical, and kinetic isotope effect experiments. The data indicate that C-O activation is facilitated by Lewis acid assistance from the boronic acid coupling partner and an ionic SN1-like mechanism accounts for oxidative addition. In this context, we demonstrate the first direct observation of oxidative addition to a quinolinium salt. Notably, this mechanism is distinct from the more commonly described SN2(‘)-type oxidative addition of low-valent transition metals to most allylic electrophiles.

Application of 166330-10-5. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 166330-10-5, Name is (Oxybis(2,1-phenylene))bis(diphenylphosphine). In a document type is Article, introducing its new discovery.

The controllable tuning of the excited states in a series of phosphine-oxide hosts (DPExPOCzn) was realized through introducing carbazolyl and diphenylphosphine-oxide (DPPO) moieties to adjust the frontier molecular orbitals, molecular rigidity, and the location of the triplet excited states by suppressing the intramolecular interplay of the combined multi-insulating and meso linkage. On increasing the number of substituents, simultaneous lowering of the first singlet energy levels (S1) and raising of the first triplet energy levels (T1, about 3.0 eV) were achieved. The former change was mainly due to the contribution of the carbazolyl group to the HOMOs and the extended conjugation. The latter change was due to an enhanced molecular rigidity and the shift of the T1 states from the diphenylether group to the carbazolyl moieties. This kind of convergent modulation of excited states not only facilitates the exothermic energy transfer to the dopants in phosphorescent organic light-emitting diodes (PHOLEDs), but also realizes the fine-tuning of electrical properties to achieve the balanced carrier injection and transportation in the emitting layers. As the result, the favorable performance of blue-light-emitting PHOLEDs was demonstrated, including much-lower driving voltages of 2.6 V for onset and 3.0 V at 100 cd m -2, as well as a remarkably improved E.Q.E. of 12.6 %.

A series of tridentate anilido-imine [N,N,O] ligands 2-(2-(R 12-2,6-C6H3NH)C6H 4)HC=N(4-tBu-6-R2-C6H2OH) [R1 = Me, R2 = tBu (LaH 2); R1 = Et, R2 = tBu (L bH2); R1 = iPr, R2 = tBu (LcH2); R1 = Me, R2 = Ad (LdH2); R1 = Et, R2 = Ad (L eH2); R1 = iPr, R2 = Ad (LfH2)] were synthesized and characterized. Reaction of the free ligand LdH2 with TiCl4 in toluene at low temperature affords the zwitterionic complex Ld+H 2Ti-Cl4 (1d). The zwitterionic complex can be dissolved in THF to form THF-solvated complex 1d?. Heating 1d in toluene at 40 C affords the neutral complex LdHTiCl3 (2d) by losing a HCl. Complex 2d can be fully converted to the final complex L dTiCl2 (3d) at 140 C under vacuum by losing another HCl. Complexes 3a-3c, 3e, and 3f were also synthesized in high yields in the same one-pot procedure. All complexes were characterized by 1H and 13C NMR spectroscopy, and the molecular structures of 1d?, 3b, 3d, and 3e were determined by single-crystal X-ray diffraction analysis. The titanium centers in complexes 3b, 3d, and 3e are five-coordinated with a geometry situated between trigonal bipyramid and square pyramid. Upon activation with alkylaluminum and Ph3C+B(C6F 5)4-, complexes 3a-3f exhibit moderate catalytic activity for ethylene polymerization.

Further fluorescence spectroscopy, photocatalytic properties and terahertz time-domain spectra (THz-TDS) were performed on 2?6. Complexes 1?3 and 6 were binuclear, while 4 was mononuclear. Complex 5 was a coordination polymer, displaying a one-dimensional infinite chain. Moreover, complexes 1, 2 and 4 were assembled via several pairs of C?H?pi interactions to 1D?3D supramolecular architectures. The emission peaks of the complexes 2?4 all exhibit a large degree of red shift, which may be tentatively attributed to the intraligand transition. Compounds 2?6 represented the first examples of Ag(I) complexes bearing both diphosphine and diimine ligands that exhibit high, efficient photocatalytic abilities for dye degradation under UV light and show good stability toward photocatalysis.

The nickel-catalyzed cyclization of bisphosphine derivatives to form various phosphacycles is reported. The reaction proceeds via the cleavage of two carbon-phosphorus bonds of the bisphosphine. Unlike the previously reported palladium catalysts, the use of nickel as a catalyst allows for the cyclization that requires C(alkyl)-P bond cleavage. A phospha-nickelacycle intermediate was successfully isolated and characterized by X-ray crystallography.

The development of an anti-Markovnikov-selective hydroamination of unactivated alkenes is a significant challenge in organometallic chemistry. Herein, we present the rhodium-catalyzed anti-Markovnikov-selective hydroamination of homoallylic amines. The proximal Lewis basic amine serves to promote reactivity and enforce regioselectivity through the formation of the favored metallacycle, thus over-riding the inherent reactivity of the alkene. The scope of both the amine nucleophiles and homoallylic amines that participate in the reaction is demonstrated.
