Abstract

Depending on the substituent at the triple bond, the reaction of 1-(alk-1-ynyl)-1-chlorocyclopropanes 1 with lithium monoalkylamides in THF gives hitherto unknown conjugated iminocyclopropenes 2 or 4-substituted 1,1-dimethylbuta-1,2-dienes 3 in up to 60% yields.

Non-secretory multiple myeloma with unusual TFG-ALK fusion showed dramatic response to ALK inhibition

Ashiq Masood, Trevor Christ, Samia Asif, Priya Rajakumar, Beth A. Gustafson, Leyla O. Shune, Ameen Salahudeen, Drew Nedvad, Suparna Nanua, Agne Paner, Timothy M. Kuzel, Mia Levy, Janakiraman Subramanian, Shahzad Raza

Summary: Non-secretory multiple myeloma (NSMM) is a distinct type of multiple myeloma characterized by the absence of detectable monoclonal protein. A case study reported here showed a relapsed and refractory NSMM patient with TFG-ALK fusion and brain metastasis had a dramatic and durable response to commercially available ALK inhibitors, highlighting the beneficial role of molecular profiling in this target-poor disease.

Unusual rearrangement-remercuration reactions of allylic silanols

Someshwar Nagamalla, Ranjeet A. Dhokale, Frederick J. Seidl, Joel T. Mague, Shyam Sathyamoorthi

Summary: The first examples of rearrangement reactions of allylic silanol substrates into linear ketone and 5-membered cyclic silanediol organomercurial products are presented in this study. The reactions are mediated by Hg(OTf)(2) and show differences in the use of base, solvent, and temperature. Mechanistic studies suggest that these products result from a series of cascading transformations in one pot, with a DFT analysis providing insights into the rearrangement process.

Electrophilic hydrophosphonylation of aldimines with alkylphosphonochloridates provides access to (E)-alk-1-enylphosphonamidates

Zhicheng Fu, Yelong Lei, Fang Sun, Jiaxi Xu

Summary: A new strategy for the synthesis of various alpha,beta-unsaturated (E)-alkenylphosphonamidates was proposed, which involved a tandem reaction sequence without the need for external hydride donors. The reaction showed excellent stereo- and regioselectivities, providing a mild and efficient method for the preparation of (E)-alk-1-enylphosphonamidates.

A novel organic anode with 14 electrons participating in redox reactions prepared under mild conditions

Xiang Li, Wei Liu, Yan Wang, Linze Lv, Huaiwei Feng, Weibo Huang, Yu Sun, Weixing Xiong, Honghe Zheng

Summary: Covalent organic frameworks (COFs) have great potential as electrode materials for high-performance lithium-ion batteries (LIBs), due to their easy structure control, abundant tunable porous structures, and reversible redox behavior of electroactive organic groups. However, most reported COFs have low capacity due to the inability of the backbone moiety's aromatic conjugated structure to participate in redox reactions. In this study, an imine bond-rich COF (TAACOF) with reversible Li-ion bonding was developed, which greatly improved the electrode capacity by inducing lithium ions to combine with the aromatic conjugated structure.

Quantifying the apparent electron transfer number of electrolyte decomposition reactions in anode-free batteries

Ming-Yue Zhou, Xiao-Qing Ding, Jun-Fan Ding, Li-Peng Hou, Peng Shi, Jin Xie, Bo-Qua Li, Jia-Qi Huang, Xue-Qiang Zhang, Qiang Zhang

Summary: Solid electrolyte interphase (SEI) is crucial for the stability of non-aqueous batteries. However, the quantitative understanding of electrolyte decomposition mechanism is limited. In this study, the apparent electron transfer number (ETN) is obtained as a quantitative descriptor in lithium metal batteries, providing insights into the decomposition mechanism of electrolyte components.

Summary: In this study, it was shown that a kinetically stabilized benzoborirene 1 can react with trimethylphosphine oxide, acetaldehyde, and tert-butyl isonitrile. The reaction with trimethylphosphine oxide resulted in the formation of benzo[c][1,2,5]oxaphosphaborole, which exhibited a long apical PO bond. The reactivity of benzoborirene 1 was consistent with computational analyses.

Adsorption-catalysis design with cerium oxide nanorods supported nickel-cobalt-oxide with multifunctional reaction interfaces for anchoring polysulfides and accelerating redox reactions in lithium sulfur battery

Sakibul Azam, Zhen Wei, Ruigang Wang

Summary: The charge and discharge mechanisms in lithium sulfur batteries are complex and involve multiple reactions. CeO2 nanorods supported bimetallic nickel cobalt oxide (NiCo2Ox) can restrain the shuttle of polysulfides and stimulate rapid redox reactions in lithium sulfur batteries. The battery with NiCo2Ox/CeO2 nanorods demonstrates high discharge capacity, stable cycling, low voltage polarization, and high sulfur utilization.
