Iron-catalyzed hydrogenation has drawn much attention, yet the scope and chemoselectivity of iron catalysis warrant further improvement. Here we report new iron pincer complexes as chemoselective hydrogenation and transfer hydrogenation catalysts. Several ...
The non-steroidal anti-inflammatory and anti-arthritic drug piroxicam (LH) reacts with arene ruthenium dichloride dimers in refluxing dichloromethane to give the complexes [(eta(6)-arene)Ru(eta(2)-N,O-L)Cl] (3: arene = C6H5Me, 4: arene = p-MeC6H4Pri, 5: ar ...
Two triphenyltin(IV) adducts of difunctional ligands, N-(n-pyridinyl) diphenylphosphinic amide (n = 2 and 4), have been synthesized and characterized by H-1, P-31, Sn-119 NMR and IR spectroscopy. The spectroscopic properties of the complexes were compared ...
We report the design, synthesis and computational investigation of a class of Ru(II)-dyes based on mixed bipyridine ligands for use in dye-sensitized solar cells. These dyes are designed to preserve the optimal anchoring mode of the prototypical N719 sensi ...
Results of electron spin resonance studies of copper pyrimidine dinitrate (Cu-PM, [PM-Cu(NO3)(2)(H2O)(2)] (n) , PM = pyrimidine), a spin-1/2 antiferromagnetic chain material with alternating g-tensor and Dzyaloshinskii-Moriya interactions, in pulsed magnet ...
Tandem reactions for the efficient synthesis of multifunctionalized 1,2,3,4-tetrahydropyridines, 2,3-dihydropyridin-4(1H)-ones, and pyridine derivatives have been developed and reaction mechanisms have been investigated. Synthetic cascades are initiated by ...
A novel strategy for de novo synthesis of pyridines featuring an unprecedented a-addition of aldehyde and enamide to isonitrile as a key step is described. Under mild conditions, a cascade reaction involving Zn(OTf)(2)-promoted [1 + 5] cycloaddition of iso ...
An efficient method has been developed for the direct amidification of carboxylic acids via sulfinylamides preformed in situ by the reaction of pure amines with prop-2-ene-1-sulfinyl chloride. The method can be applied to aliphatic acids, including pivalic ...
Reduction of CO2 by electrochemical and photoelectrochemical methods to produce carbon-rich fuels is a heavily pursued research theme. Most of the current efforts are focused on the development of transition-metal-based catalysts. In this tutorial review, ...
A reaction of 2-acyl substituted tetrahydroquinolines, prepared by Lewis acid-catalyzed three-component reaction of α-oxo aldehydes, anilines, and dienophiles, with in situ generated arynes afforded 5,6-dihydroindolo[1,2-a]- quinolines in good to excellent ...
