Pan, Lei;Kelley, Alexandra S.;Cooke, Maria Victoria;Deckert, Macy M.;Laulhe, Sebastien research published 《 Transition-Metal-Free Photoredox Phosphonation of Aryl C-N and C-X Bonds in Aqueous Solvent Mixtures》, the research content is summarized as follows. Herein, the authors present an efficient and mild methodol. for the synthesis of aromatic phosphonate esters in good to excellent yields using 10H-phenothiazine, an inexpensive commodity chem., as a photoredox catalyst. The reaction exhibits wide functional group compatibility enabling the transformation in the presence of ketone, amide, ester, amine, and alc. moieties. Importantly, the reaction proceeds using a green solvent mixture primarily composed of H₂O, thus lowering the environmental footprint of this transformation compared to current methods. The transformation also proceeds under atm. conditions, which further differentiates it from current methods that require inert atm. Mechanistic work using fluorescence quenching experiments and radical trapping approaches support the proposed mechanism.

Pan, Lei;Cooke, Maria Victoria;Spencer, Amara;Laulhe, Sebastien research published 《 Dimsyl Anion Enables Visible-Light-Promoted Charge Transfer in Cross-Coupling Reactions of Aryl Halides》, the research content is summarized as follows. A methodol. is reported for visible-light-promoted synthesis of unsym. chalcogenides enabled by dimsyl anion in the absence of transition-metals or photoredox catalysts. The cross-coupling reaction between aryl halides and diaryl dichalcogenides proceeds with electron-rich, electron-poor, and heteroaromatic moieties. Mechanistic investigations using UV-Vis spectroscopy, time-dependent d. functional theory (TD-DFT) calculations, and control reactions suggest that dimsyl anion forms an electron-donor-acceptor (EDA) complex capable of absorbing blue light, leading to a charge transfer responsible for generation of aryl radicals from aryl halides. This previously unreported mechanistic pathway may be applied to other light-induced transformations performed in DMSO in the presence of bases and aryl halides.

Pan, Pan;Liu, Shihan;Lan, Yu;Zeng, Huiying;Li, Chao-Jun research published 《 Visible-light-induced cross-coupling of aryl iodides with hydrazones via an EDA-complex》, the research content is summarized as follows. A visible-light-induced, transition-metal and photosensitizer-free cross-coupling of aryl iodides RI (R = Ph, naphthalen-1-yl, thiophen-3-yl, 4-phenylmorpholine, etc.) with hydrazones R¹CH=NNH₂ (R¹ = Ph, naphthalen-1-yl, pyridin-2-yl, 2H-1,3-benzodioxol-5-yl, etc.) was developed. In this strategy, hydrazones were used as alternatives to organometallic reagents, in the absence of a transition metal or an external photosensitizer, making this cross-coupling mild and green. The protocol was compatible with a variety of functionalities, including Me, methoxy, trifluoromethyl, halogen, and heteroaromatic rings. Mechanistic investigations showed that the association of the hydrazone anion with aryl halides formed an electron donor-acceptor complex, which when excited with visible light generated an aryl radical via single-electron transfer.

(Z)-selective semihydrogenation of alkynes were achieved using a copper nanocatalyst which was generated in situ by adding ammonia borane to an ethanol solution of copper sulfate. Different types of alkynes including aryl-aryl, aryl-alkyl, and aliphatic alkynes were selectively reduced to (Z)-alkenes affording up to 99% isolated yield. The semihydrogenation of terminal alkynes to alkenes and gram-scale applications were also reported. In addition to eliminating catalyst preparation, the proposed approach were simple and practical and served as a suitable alternative method to the conventional Lindlar catalyst.

M.;Jennings, Julia J.;Franz, Annaliese K. research published 《 NMR Quantification of Hydrogen-Bond-Accepting Ability for Organic Molecules》, the research content is summarized as follows. The hydrogen-bond-accepting abilities for more than 100 organic mols. are quantified using ¹⁹F and ³¹P NMR spectroscopy with pentafluorobenzoic acid (PFBA) and phenylphosphinic acid (PPA) as com. available, inexpensive probes. Anal. of pyridines and anilines with a variety of electronic modifications demonstrates that changes in NMR shifts can predict the secondary effects that contribute to H-bond-accepting ability, establishing the ability of PFBA and PPA binding to predict electronic trends. The H-bond-accepting abilities of various metal-chelating ligands and organocatalysts are also quantified. The measured Δδ(³¹P) and Δδ_p(¹⁹F) values correlate strongly with Hammett parameters, pK_a of the protonated HBA, and proton-transfer basicity (pK_BH+).
