Summary: A novel series of heterometallic f-block-frameworks, including the first examples of transuranic heterometallic U-238/Pu-239-MOFs, and a novel monometallic Pu-239-analog, were reported. The kinetics and thermodynamics of heterometallic actinide-MOF formation were probed, with the first value of a U-to-Th transmetallation rate reported. Density of states, enthalpy of formation, band gap, proton affinity, and thermal/chemical stability were investigated as a function of metal ratios.

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.

Summary: In this study, three representative Li-alloys were investigated, and it was found that solid-solution phases have lower phase-transition energy barriers compared to intermetallic compounds, resulting in higher Li-alloying/dealloying reversibility and cycling stability. These effects enable the formation of a homogeneous alloy phase and provide important guidelines for the intelligent design of components for secondary metal batteries.

Summary: The study reports thermally induced, transition-metal-free metathesis of unsymmetrically substituted digermenes. The use of tethered auxiliary donors helps stabilize the transient germylene fragments, promoting the metathesis reaction. Density functional theory calculations reveal the thermodynamic driving force of the metathesis and the crucial role of tethered donors in the reaction. The bridged tetragermadiene precursor can also undergo heavier acyclic diene metathesis polymerization, similar to the carbon case, resulting in polydigermene formation.

Summary: The regiodivergent reaction of phenylacetylene with various disilenes and bridged tetrasiladienes was studied, revealing that the regioselectivity of the [2+2] cycloaddition strongly depends on the nature of the substituent R. The presence of catalytic quantities of base suppresses cycloaddition in favor of the formal CH addition of phenylacetylene. Intermediacy of an alkynyl-substituted disilanyl lithium suggests a carbolithiation pathway for the net CH addition.

Summary: The synthesis of p-methylthio-functionalized disilenes with (oligo)phenylene-linkers of different sizes was reported, with Si-29 NMR and UV/vis data suggesting that the linker-size only moderately affects the Si=Si moiety. Cyclic voltammetry showed an increasing number of reduction events with the number of phenylene rings, clearly associated with the oligo(phenylene) linking unit. Significant differences in the exchange current density of oxidation and reduction reactions were observed between the prepared disilenes using linear sweep voltammetry with a rotating disc electrode.

Summary: Schnockel's [(AlCp*)(4)] and Jutzi's [SiCp*][B(C6F5)(4)] are important in modern main-group chemistry with various applications in synthesis and catalysis. However, the reactivity between AlCp* and [SiCp*](+) has not been explored. In this study, their reaction was investigated and complex salts [Cp*Si(AlCp*)(3)][WCA] were obtained. The tetrahedral [SiAl3](+) core not only represents a rare example of a low-valent silicon-doped aluminium-cluster, but also provides a convenient preparative entry towards low-valent Si-Al clusters.

Summary: By a series of addition and reduction reactions, the synthesis of a structurally rare silapyramidane compound was achieved from an amidinate-supported silylene and tetrakis(trimethylsilyl)cyclobutadiene as starting materials. The silapyramidane compound exhibited an unusually shielded 29Si NMR resonance at -448.3 ppm for the apex silicon atom. Treatment of the silapyramidane with Fe2(CO)9 resulted in the formation of the corresponding silapyramidane-iron complex. Moreover, the silapyramidane also underwent a reaction with the cyclobutadiene starting material to afford a fluorescent spirobis(silole) compound.

Summary: A straightforward synthesis of the first peraryl diboriranide was reported, demonstrating its preference for s-type coordination modes towards main group and transition metal centers. The synthesis involved the preparation of the non-classical diborirane from a readily available 1,2-dichlorodiborane(4) and subsequent conversion to the peraryl diboriranide lithium salt in three steps. Representative complexes with tin, copper, gold, and zinc were prepared and characterized to illustrate the reactivity and complexation behavior of the diboriranide.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
