Basicity of N ‐(Tetramesityltetraphosphacyclopentylidene)cyclohexylamine: An Unusual Diphospha(III)guanidine Derivative

Published: 22 September 2017

Author(s): Anup Kumar Adhikari, Toni Grell, Peter Lönnecke, Evamarie Hey‐Hawkins

The nitrogen atom in cyclic hetero‐oligophosphane cyclo‐P4Mes4C(NCy) (1) can be protonated with HCl or HBF4. The resulting cation was isolated as the BF4–, AlCl4– and GaCl4– salts and characterised by NMR spectroscopy, mass spectrometry and X‐ray crystallography. According to quantum mechanical calculations, the basicity of compound 1 is comparable to that of methyl‐substituted monophospha(III)guanidine. The pKα value of 1 was also determined experimentally with...

Online Monitoring of Polymerizations: Current Status

Published: 22 September 2017

Author(s): Joris J. Haven, Tanja Junkers

Polymerizations are challenging to monitor online. Next to spectrometric information, which indicates the composition, progress, and identity of polymers, other characterization methods also need to be employed for paramount monitoring. Information on molecular weight distributions and end group patterns are often indispensable for accurate process (and product) control. An overview of existing characterization methods, which can be used...

Effect of Formamidinium/Cesium Substitution and PbI 2 on the Long‐Term Stability of Triple‐Cation Perovskites

Published: 22 September 2017

Author(s): Shashwat Shukla, Sudhanshu Shukla, Lew Jia Haur, Sai S. H. Dintakurti, Guifang Han, Anish Priyadarshi, Tom Baikie, Subodh G. Mhaisalkar, Nripan Mathews

Abstract Altering cation and anion ratios in perovskites has proven an excellent means of tuning the perovskite properties and enhancing the performance. Recently, methylammonium/formamidinium/cesium triple‐cation mixed‐halide perovskites have demonstrated efficiencies up to 22 %. Similar to the widely explored methylammonium lead halide, excess PbI2 is added to these perovskite films to enhance their performances. The excess PbI2 is known to...

C−H Cyanation of 6‐Ring N‐Containing Heteroaromatics

Published: 22 September 2017

Author(s): Bryony L. Elbert, Alistair J. M. Farley, Timothy W. Gorman, Tarn C. Johnson, Christophe Genicot, Bénédicte Lallemand, Patrick Pasau, Jakub Flasz, José L. Castro, Malcolm MacCoss, Robert S. Paton, Christopher J. Schofield, Martin D. Smith, Michael C. Willis, Darren J. Dixon

Abstract Heteroaromatic nitriles are important compounds in drug discovery, both for their prevalence in the clinic and due to the diverse range of transformations they can undergo. As such, efficient and reliable methods to access them have the potential for far‐reaching impact across synthetic chemistry and the biomedical sciences. Herein, we report an approach to heteroaromatic C−H cyanation through triflic anhydride activation,...

Synthesis and Reactivity of a Scandium Terminal Hydride: H 2  Activation by a Scandium Terminal Imido Complex

Published: 22 September 2017

Author(s): Xianghao Han, Li Xiang, Carlos A. Lamsfus, Weiqing Mao, Erli Lu, Laurent Maron, Xuebing Leng, Yaofeng Chen

Abstract Dihydrogen is easily activated by a scandium terminal imido complex containing the weakly coordinated THF. The reaction proceeds through a 1,2‐addition mechanism, which is distinct from the σ‐bond metathesis mechanism reported to date for rare‐earth metal‐mediated H2 activation. This reaction yields a scandium terminal hydride, which is structurally well‐characterized, being the first one to date. The reactivity of this...

In‐Situ Fabrication of MOF‐Derived Co−Co Layered Double Hydroxide Hollow Nanocages/Graphene Composite: A Novel Electrode Material with Superior Electrochemical Performance

Published: 22 September 2017

Author(s): Xue Bai, Jingyuan Liu, Qi Liu, Rongrong Chen, Xiaoyan Jing, Bin Li, Jun Wang

Abstract Rational design of a transition metal layered double hydroxide (LDH) and graphene composite is vitally important for designing high‐performance supercapacitor electrodes. Although various methods are performed, the realization of high‐performance is still impeded by the agglomeration of graphene and layered double hydroxide. Here, metal–organic framework derived cobalt–cobalt layered double hydroxide (Co−Co LDH) hollow...

Ribbon‐like Foldamers for Cellular Uptake and Drug Delivery

Published: 22 September 2017

Author(s): Lubomir L. Vezenkov, Vincent Martin, Nadir Bettache, Matthieu Simon, Alexandre Messerschmitt, Baptiste Legrand, Jean‐Louis Bantignies, Gilles Subra, Marie Maynadier, Virginie Bellet, Marcel Garcia, Jean Martinez, Muriel Amblard

Abstract Different intracellular delivery systems of bioactive compounds have been developed, including cell‐penetrating peptides. Although usually nontoxic and biocompatible, these vectors share some of the general drawbacks of peptides, notably low bioavailability and susceptibility to protease degradation, that limit their use. Herein, the conversion of short peptide sequences into poly‐α‐amino‐γ‐lactam foldamers that adopt a...

Aromatic Halogenation by Using Bifunctional Flavin Reductase–Halogenase Fusion Enzymes

Published: 22 September 2017

Author(s): Mary C. Andorfer, Ketaki D. Belsare, Anna M. Girlich, Jared C. Lewis

Abstract The remarkable site selectivity and broad substrate scope of flavin‐dependent halogenases (FDHs) has led to much interest in their potential as biocatalysts. Multiple engineering efforts have demonstrated that FDHs can be tuned for non‐native substrate scope and site selectivity. FDHs have also proven useful as in vivo biocatalysts and have been successfully incorporated into biosynthetic pathways to build new chlorinated...

Organocatalytic Synthesis of Lactones by the Oxidation of Alkenoic Acids

Published: 22 September 2017

Author(s): Ierasia Triandafillidi, Marianna Raftopoulou, Anatoli Savvidou, Christoforos G. Kokotos

Abstract Along the lines of modern sustainable oxidation, a green and mild organocatalytic synthetic procedure for the synthesis of hydroxylactones from alkenoic acids is described. The reaction includes the activation of H2O2 by an organocatalyst (2,2,2‐trifluoromethylacetophenone), the oxidation of an olefinic group to the corresponding epoxide, and intramolecular lactonization to afford a variety of substituted γ‐ or δ‐lactones with multiple...

Isomerizing Hydroformylation of Cashew Nut Shell Liquid

Published: 22 September 2017

Author(s): Swechchha Pandey, Dinesh R. Shinde, Samir H. Chikkali

Abstract A small library of bisphosphorus ligands was evaluated in the rhodium‐catalyzed isomerizing hydroformylation (I‐HF) of cashew nut shell liquid (CNSL). The rhodium complex of 1,2‐bis((di‐tert‐butylphosphanyl)methyl)benzene (BDTBPMB; L4) outperformed the other bisphosphite and bisphosphine ligands and unveiled a moderate selectivity of 28 % and 50 % in the I‐HF of CNSL monoene and methoxy‐protected monoene, respectively. The resultant...
