1. Mechanism of copper-free Sonogashirareaction operates through palladium-palladium transmetallation

Martin Gazvoda, Miha Virant, Balazs Pinter& Janez Košmrlj

https://www.nature.com/articles/s41467-018-07081-5

Although the Sonogashira coupling ofacetylenes and vinyl/aryl halides has been applied for decades, manymechanistic questions have remained unanswered. Here, the authors provideexperimental and theoretical support for two interlinked palladium cyclesoperating in the debated Sonogashira coupling mechanism.

2. Samarium(II) folding cascades involvinghydrogen atom transfer for the synthesis of complex polycycles

https://www.nature.com/articles/s41467-018-07194-x

Diversity-oriented synthesis is a valuablestrategy to construct complex molecules of medicinal interest. Here, theauthors show a folding cascade strategy to convert linear substrates intopolycyclic compounds with multiple stereocentres by combining the reductivechemistry of SmI2 with 1,5-hydrogen atom transfer.

3. Manganese-catalyzed hydroboration ofcarbon dioxide and other challenging carbonyl groups

Christina Erken, Akash Kaithal, Suman Sen,Thomas Weyhermüller, Markus Hölscher, Christophe Werlé & Walter Leitner

https://www.nature.com/articles/s41467-018-06831-9

Catalytic reduction of CO2 and biomassderivatives is of great current interest from a sustainable chemistryperspective. Here, the authors report a manganese pincer complex able to reduceunder mild conditions carboxylic acids, carbonates and even carbon dioxideusing pinacolborane as reducing agent.

4. Defluorosilylation of fluoroarenes andfluoroalkanes

Benqiang Cui, Shichong Jia, Etsuko Tokunaga& Norio Shibata

https://www.nature.com/articles/s41467-018-06830-w

Transformation of strong C-F bonds intoC-Si bonds is an extremely useful strategy for further derivatization oforganic molecules. Here, the authors report a nickel-catalyzed strategy toconvert aryl fluorides into sylylated arenes while defluorosilylation of alkylfluorides is achieved under metal-free conditions.

5. Total syntheses of shizukaols A and E

Jian-Li Wu, Yin-Suo Lu, Bencan Tang &Xiao-Shui Peng

https://www.nature.com/articles/s41467-018-06245-7

Shizukaols, bioactive dimers naturallyoccurring in the Chloranthaceae family, possess a complex polycyclic frameworkwith more than ten contiguous stereocenters. Here the authors report the totalsyntheses of shizukaols A and E achieved via a modified Diels–Alder reactionmimicking the biosynthetic pathway.

6. A flow platform for degradation-freeCuAAC bioconjugation

Marine Z. C. Hatit, Linus F. Reichenbach, John M. Tobin, Filipe Vilela, Glenn A. Burley & Allan J. B. Watson

https://www.nature.com/articles/s41467-018-06551-0

Cu-catalyzed azide-alkyne cycloaddition(CuAAC) reaction is a common bioconjugation technique; however oxidativedegradation and residual copper may limit its use. Here, the authors show thatppm levels of Cu, generated in situ by solvent-mediated pipe erosion in flow,catalyze the CuAAC reaction with no product degradation.

1. Breaking the scaling relationship viathermally stable Pt/Cu single atom alloys for catalytic dehydrogenation

Guodong Sun, Zhi-Jian Zhao, Rentao Mu, Shenjun Zha, Lulu Li, Sai Chen, Ketao Zang, Jun Luo, Zhenglong Li, Stephen C. Purdy, A. Jeremy Kropf, Jeffrey T. Miller, Liang Zeng & Jinlong Gong

https://www.nature.com/articles/s41467-018-06967-8

Enhancing the catalytic activity ofnoble-metal alloys is frequently accompanied by side reactions. Here, theauthors describe an approach to break the scaling relationship for propanedehydrogenation, by assembling single atom alloys, to achieve simultaneousenhancement of propylene selectivity and propane conversion.

2. Deconvolution of octahedral Pt₃Ninanoparticle growth pathway from in situ characterizations

Xiaochen Shen, Changlin Zhang, Shuyi Zhang, Sheng Dai, Guanghui Zhang, Mingyuan Ge, Yanbo Pan, Stephen M. Sharkey, GeorgeW. Graham, Adrian Hunt, Iradwikanari Waluyo, Jeffrey T. Miller, Xiaoqing Pan& Zhenmeng Peng

https://www.nature.com/articles/s41467-018-06900-z

Understanding the growth pathway of facetedalloy nanoparticles at the atomic level is crucial to morphology control andproperty tuning, but remains a challenge. Here, the authors reveal the particlegrowth and facet formation mechanisms of octahedral Pt3Ni nanoparticles usingmultiple cutting-edge in situ techniques.

3. Activity enhancement of cobalt catalystsby tuning metal-support interactions

Carlos Hernández Mejía, Tom W. van Deelen& Krijn P. de Jong

https://www.nature.com/articles/s41467-018-06903-w

Tuning metal-support interaction canstrongly influence the performance of a catalyst, and is thus essential forcatalyst design. Here, the authors investigate reduction-oxidation-reductiontreatments as a method to affect metal-support interactions of cobalt-basedcatalysts in Fischer-Tropsch synthesis.

4. Lewis basicity generated by localisedcharge imbalance in noble metal nanoparticle-embedded defective metal–organicframeworks

Ying Chuan Tan & Hua Chun Zeng

https://www.nature.com/articles/s41467-018-06828-4

Interactions between metal nanoparticles(NPs) and metal–organic frameworks (MOFs) in their composite forms have provento exhibit beneficial properties. Here the authors present a unique approach toimmobilise Pd NPs and, more importantly, to generate tunable basic sites withinan anionic defective MOF.

5. Single Particle Automated Raman TrappingAnalysis
