Chiral Cyclopentadienyl Cobalt(III) Complexes Enable Highly Enantioselective 3d-Metal-Catalyzed C-H Functionalizations

Nicolai Cramer, Yun-Suk Jang, Kristers Ozols

The synthesis of a set of cobalt(III)-complexes equipped with trisubstituted chiral cyclopentadienyl ligands is reported, and their steric and electronic parameters are mapped. The application potential of these complexes for asymmetric C-H functionalizati ...

One-step access to N-enoxyimides by gold-catalysed addition of N-hydroxyimides to terminal alkynes

Nicolai Cramer, Coralie Danielle Annick Duchemin

N-Enoxyimides have become attractive substrates for novel catalytic transformations, yet their tedious multi-step synthesis hampers full exploitation of their synthetic potential. We report a gold(I)-catalyzed protocol to access N-enoxyimides from simple a ...

Versatile Route to trans-Platinum(II) Complexes via Manipulation of a Coordinated 3-(Pyridin-3-yl)propanoicAcid Ligand

Paul Joseph Dyson, Tina Riedel, Marta Maroto Diaz

We describe the direct coupling of alcohols and amines to a 3-(pyridin-3-yl)propanoic acid ligand coordinated to a Pt(II) to afford ester and amide derivatives. Using this approach, a family of trans-Pt(II) compounds with amine ligands bearing long perfluo ...

Remote C(sp(3))-H Arylation and Vinylation of N-Alkoxypyridinium Salts to delta-Aryl and delta-Vinyl Alcohols

Qian Wang, Jieping Zhu, Xu Bao

The reaction of readily available and bench-stable N-alkoxypyridinium salts with arylboronic and vinylboronic acids afforded delta-aryl and delta-vinyl alcohols, respectively, in the presence of fac-Ir(ppy)(3) and Cu(OTf)(2) dual catalysts. The reaction ta ...

Dual Photoredox/Copper Catalysis for the Remote C(sp3 )−H Functionalization of Alcohols and Alkyl Halides by N -Alkoxypyridinium Salts

Qian Wang, Jieping Zhu, Xu Bao

Under mild dual photoredox/copper catalysis, the reaction of N-alkoxypyridinium salts with readily available silyl reagents (TMSN3, TMSCN, TMSNCS) afforded d-azido, d-cyano, and d-thiocyanato alcohols in high yields. The reaction went through a domino proc ...

Quantification methods for chloride binding in Portland cement and limestone systems

Karen Scrivener, Wei Sun, Fabien Jacques Michel Georget, Hamed Maraghechi, William Wilson, Shiyu Sui

This paper presents a comparison of methods to quantify the chloride binding capacity for cementitious materials composed of Ordinary Portland Cement (OPC) and Limestone (LS, 0 to 55% replacement). Physical and chemical chloride bindings were investigated ...

Development of new strategies to produce and characterize PceC, a membrane-bound flavoprotein involved in organohalide respiration

Christof Holliger, Lorenzo Cimmino

Halogenated organic compounds (so-called organohalides) represent one of the major widespread groundwater pollutants. Organohalide respiration (OHR) is a bacterial anaerobic process in which chlorinated compound, e.g. tetrachloroethene (PCE), is used as te ...
