Mono‐ and Polyazatriphenylene‐Based Ligands: An Updated Library of Synthetic Strategies (2001–2018)

Published: 20 August 2018

Author(s): Sougata Santra, Albert F. Khasanov, Anindita Mukherjee, Matiur Rahman, Igor S. Kovalev, Dmitry S. Kopchuk, Grigory V. Zyryanov, Adinath Majee, Oleg N. Chupakhin, Valery N. Charushin

This review surveys the most useful strategies for the synthesis of azatriphenylenes. Azatriphenylene derivatives are of considerable interest due to their promising photophysical and coordinating properties and to their presence in the composition of natural products. These scaffolds have shown ability as photoluminescent chemosensors for organic anions and nitroaromatic compounds. The straight‐forward construction of an azatriphenylene...

Meta‐Selective C–H Alkylation of 2‐Phenylpyridine Catalyzed by Ruthenium: DFT Study on the Mechanism and Regioselectivity

Published: 20 August 2018

Author(s): Lei Zhang, Lu Yu, Jianguo Zhou, Yu Chen

Density functional theory calculations have been performed to quantitatively characterize ruthenium‐catalyzed meta‐selective C–H functionalizations of 2‐phenylpyridine. The reaction with tert‐butyl bromide was used as a model, and the proposed catalytic cycle is comprised of three successive steps: C–H activation, alkylation of the ruthenacycle, and demetalation, and separation of the product, among which C–H activation is the rate‐determining step...

Selective Electron Transfer Reduction of Urea‐Type Carbonyls

Published: 20 August 2018

Author(s): Huan‐Ming Huang, David J. Procter

Urea‐type carbonyls in barbiturates undergo a highly chemoselective electron transfer reduction upon treatment with SmI2/H2O/LiBr. The process involves the formation, and further reduction, of unusual ketyl‐type radical anions under mild conditions. Cyclic aminal products are obtained in good to excellent yield without recourse to preactivation of the substrate or the use of metal hydride reagents. Furthermore, varying the protic additive used in...

Application of “Smart” Amine Donors for Rapid Screening and Scale‐Up of Transaminase‐Mediated Biotransformations

Published: 20 August 2018

Author(s): Andrew Gomm, Stylianos Grigoriou, Christopher Peel, James Ryan, Nafees Mujtaba, Thomas Clarke, Evelina Kulcinskaja, Elaine O'Reilly

The “smart” amine donors o‐xylylenediamine and cadaverine were employed for the rapid screening of a large ketone library and subsequent preparative‐scale synthesis of selected compounds using a commercially available amine transaminase, ATA256. The methodology enables both screening and preparative‐scale biotransformations to be performed with a single enzyme and simplifies the generation of sp3‐rich small‐molecule libraries. ...

Self‐Assembly Reactions To Form Multinuclear Zirconium(III) and Titanium(III) Complexes with Imidazole Derivatives as Bridging Ligands

Published: 20 August 2018

Author(s): Pia Sander, Irina Geibel, Carina Witte, Sascha Hüller, Marc Schmidtmann, Rüdiger Beckhaus

Self‐assembly reactions with low valent early transition metals, leading to neutral multinuclear complexes are rare. Mostly late transition metals like Pt, Pd or Ru together with N‐heterocycles or O‐donor‐based ligands are used to form supramolecular coordination complexes. This paper reports on self‐assembly reactions of low valent titanocene and zirconocene units and five‐membered N‐heterocycles as bridging ligands. These reactions lead to novel...

Visualization of Structural Changes During Deactivation and Regeneration of FAU Zeolite for Catalytic Fast Pyrolysis of Lignin Using NMR and Electron Microscopy Techniques

Published: 20 August 2018

Author(s): Zhiqiang Ma, Ashim Ghosh, Navinchandra Asthana, Jeroen van Bokhoven

Abstract Catalytic fast pyrolysis of pretreated lignin (with hydrogen chloride solution) over FAU (15) zeolite uniquely yielded a high fraction of phenols, phenol alkoxys, and aromatic hydrocarbons. However, the zeolite underwent rapid deactivation. This paper reports the visualization of the structural changes during deactivation and regeneration of the zeolite is reported. The deactivated and regenerated zeolites were...

A Straightforward Sequential Approach for the Enantioselective Synthesis of Optically Active α‐Arylmethanol‐1,2,3‐Triazoles

Published: 20 August 2018

Author(s): Floyd C. D. Andrade, Lucas V. B. L. Pugnal, Hugo L. I. Betim, Jéssica F. Vani, Julio Zukerman‐Schpector, Ricardo S. Schwab

Herein we describe a compelling sequential methodology for obtaining optically active α‐arylmethanols‐1,2,3‐triazoles. The approach is based on the enantioselective alkynylation of aldehydes followed by a one‐pot two‐step desilylation/CuI‐catalyzed azide‐alkyne 1,3‐dipolar cycloaddition (CuAAC), providing the corresponding products with excellent yields and high levels of enantioselectivity. Furthermore, the click chemistry can be performed without...

Photocoloration in Hybrid Amino Acid Polyoxometalates

Published: 20 August 2018

Author(s): Fateme Akhlaghi Bagherjeri, Chris Ritchie, Robert W. Gable, Colette Boskovic

The study of four different salts of a hybrid glycine–polyoxotungstate has revealed photocoloration that is dependent on the intramolecular hydrogen bonding between glycine ligand ammonium groups and the polyoxotungstate. Four compounds comprised of the hybrid polyoxometalate [As4{W3Y}W44Y4O159(Gly)8(H2O)12]9– (Gly = glycine) with glycinium, benzylammonium, 4‐methylbenzylammonium, or benzyltriethylammonium countercations have been ...

Synthesis and Avidin Binding of Ruthenium Complexes Functionalized with a Light‐Cleavable Free Biotin Moiety

Published: 20 August 2018

Author(s): Bianka Siewert, Michiel Langerman, Andrea Pannwitz, Sylvestre Bonnet

In this work the synthesis, photochemistry, and streptavidin interaction of new [Ru(tpy)(bpy)(SRR′)](PF6)2 complexes where the R′ group contains a free biotin ligand, are described. Two different ligands SRR′ were investigated: An asymmetric ligand 1 where the Ru‐bound thioether is a N‐acetylmethionine moiety linked to the free biotin fragment via a triethylene glycol spacer and a symmetrical ligand 2 containing two identical biotin moieties. The coordination of...

Chemical and Electrochemical Oxidation of Tris (3,5‐di‐ tert ‐butylphenyl)phosphine – High Z′ Crystal Structures and Conformational Effects Associated with Bulky meta Substituents

Published: 20 August 2018

Author(s): Ivelise Dimbarre Lao Guimarães, Jarem Raul Garcia, Karen Wohnrath, René T. Boeré

Synthesis and single‐crystal X‐ray diffraction structures of (3,5‐tBu2‐C6H3)3P, (3,5‐tBu2‐C6H3)3PO·H2O, (3,5‐tBu2‐C6H3)3PS and (3,5‐tBu2‐C6H3)3PSe are reported. The structure of (3,5‐tBu2‐C6H3)3P has Z′ = 4, with both M and P enantiomers of a helical conformation and a conformation with one flat ring in the same lattice. The pyramidality index, Σ{∠CPC}, is smaller for the helical compared to the flat conformers. All four have structures that are more pyramidal...
