8-(Diphenylphosphanyl)quinoline [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2010
The title compound, C(21)H(16)NP, is a known P-N chelator and various crystal structures of its metal complexes have been reported. However, no crystallographic evidence of the free ligand has been given to date. The phenyl rings are almost orthogonal to one another [dihedral angle = 88.9 (1)°], and they are twisted from the mean plane of the quinoline

Eco‐Friendly Synthesis of Cobalt Phthalocyanine for High‐Efficiency CO2${\rm CO}_{2}$ Electroreduction

open access: yesChemistry – A European Journal, EarlyView.
A sustainable synthesis of cobalt phthalocyanine (CoPc) using low‐impact solvents yields high‐performance electrocatalysts with reduced waste (E‐factor 18.6). When integrated into gas diffusion electrodes, CoPc achieves up to 12% Faradays efficiency for CO2‐to‐methanol and 65% CO2‐to‐CO conversion, aligning with state‐of‐the‐art materials and enabling ...

Stafib‐2‐CR: an Improved Nanomolar and Selective Inhibitor of the Transcription Factor STAT5b Developed by Conformational Restriction of Stafib‐2

open access: yesChemistry – A European Journal, EarlyView.
Conformational restriction strategies to increase the activity and selectivity of the STAT5b inhibitor Stafib‐2 are presented. The best conformationally restricted inhibitor Stafib‐2‐CR has threefold higher activity against STAT5b than Stafib‐2. A cell‐permeable prodrug of Stafib‐2‐CR inhibits phosphorylation of STAT5b in cultured human leukemia cells ...

Expedient Discovery of a Metallaphotoredox Cyanomethylation for Synthesizing α‐Aryl Nitriles

open access: yesChemistry – A European Journal, EarlyView.
A metallaphotoredox cyanomethylation reaction has been developed for the synthesis of valuable α‐aryl nitrile intermediates. The methodology was successfully applied to diverse medicinally‐relevant substrates, providing an expedient route to anti‐cancer Senexin compounds, while also removing the need for toxic cyanide reagents. The mechanism was probed

Photoinduced Hydrogenative Dearomatization With Homocoupling of Quinolines to Construct Octahydro‐4,4'‐biquinolines

open access: yesChemistry – A European Journal, EarlyView.
Dearomative homocoupling of quinolines into 1,1',2,2',3,3',4,4'‐octahydro‐4,4'‐biquinoline (OHBQ) is reported. The photoexcited boron complex, in situ generated from quinoline, HB(pin), and KOtBu, enables the unprecedented homocoupling of tetrahydroquinolines that is challenging in the ground state, expanding the chemical diversity of OHBQ derivatives.

Phosphorescence of Heavy, T‐Shaped Pnictogen Trisamides in Solution at Room Temperature in the Near‐Infrared II Region

open access: yesChemistry – A European Journal, EarlyView.
The unique photophysical properties of heavy T‐shaped Sb and Bi trisamides are reported. A ligand‐to‐pnictogen charge‐transfer excitation from a redox‐active NNN pincer to a vacant pnictogen p‐orbital populates a triplet state that emits in the highly desirable NIR‐II region, with lifetimes up to the µs range.
