Conformational study of 2-(2-pyrrolyl)pyridine and 2,6-di(2-pyrrolyl) pyridine was performed on the basis of the experimental measurements and high-level ab initio calculations of the one-bond 13C-13C, 13C-1H an

To explore structure-activity relationships with respect to light-harvesting behavior, a family of neutral iridium complexes [Ir(ppy)2(LR)] 1-4 (where ppy = 2-phenylpyridine, and NN = 2-(1H-pyrrol-2-yl)pyridine and its functionalized derivatives) were designed and synthesized. The structural modifications in metal complexes are accomplished through the attributions of electron-donating CH3 in 2, OCH3 in 3, and electron-withdrawing CF3 in 4. The structural analysis displays that the pyridylpyrrole acts as one-negative charged bidentated ligand to chelate the iridium center. The electrochemical and photophysical properties of these complexes were systematically studied. The neutral 1-4 as well as the ionic structurally analogous [Ir(ppy)2(bpy)](PF6) (5) were utilized as PSs in photocatalytic hydrogen generation from water with [Co(bpy)3](PF6)2 as catalyst and triethanolamine (TEOA) as electron sacrificial agent in the presence of salt LiCl. Complex 1 maintains activity for more than 144 h under irradiation, and the total turnover number is up to 1768. The electrochemical properties and the quenching reaction indicate the H2 generation by neutral complexes 1-4 is involved exclusively in the oxidative quenching process.
Conformational equilibria and photoinduced tautomerization in 2-(2′-pyridyl)pyrrole

Depending on the polarity and protic abilities of the solvent, 2-(2′-pyridyl)pyrrole can exist in either syn or anti rotameric forms. In nonpolar solvents, intramolecular excited state single proton transfer is observed, manifested by the appearance of low-energy tautomeric emission. The solvent-assisted excited state double proton transfer reaction is also detected. DFT calculations confirm low barriers for both single and double proton transfer processes in the lowest excited singlet state and show different character of the tautomerization in both cases: in the intramolecular reaction, mutual approach of two nitrogen atoms plays an important role.
Intercepting a transient non-hemic pyridine: N -oxide Fe(iii) species involved in OAT reactions

In the context of bioinspired OAT catalysis, we developed a tetradentate dipyrrinpyridine ligand, a hybrid of hemic and non-hemic models. The catalytic activity of the iron(iii) derivative was investigated in the presence of iodosylbenzene. Unexpectedly, MS, EPR, M?ssbauer, UV-visible and FTIR spectroscopic signatures supported by DFT calculations provide convincing evidence for the involvement of a relevant FeIII-O-NPy active intermediate.

Synthesis of Decahydrocyclobuta[cd]indene Skeletons: Rhodium(III)-Catalyzed Hydroarylation and Relay Thiophene-Promoted Intramolecular [2+2] Cycloaddition

The preparation of decahydrocyclobuta[cd]indene skeleton was accomplished through rhodium(III)-catalyzed hydroarylation and relay thiophene-promoted intramolecular [2+2] cycloaddition. This tandem reaction exhibited broad substrate scope (24 examples) and good functional group compatibility. Control experiments revealed the important role of sulfur (S) heteroatom, thus a tentative mechanism with thiophene-promoted double Michael additions was proposed to explain this formal [2+2] cycloaddition. Moreover, the resulting polycyclic products displayed potent anti-cancer activities against breast cancer cell lines MDA-MB-468. (Figure presented.).
