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 paper presents a chemical strategy for obtaining nanoparticles of the RbxMn[Fe(CN)(6)]((x+2)/3)center dot nH(2)O (RbMnFe) Prussian blue analogue in a direct manner, aiming to maintain its switching ability at the nanoscale. The study found that smaller particles had lower rubidium content, potentially affecting the observation of switching properties on very small particles. The results show the potential for creating switchable particles without surfactants, and the importance of this work in processing nanoparticles into devices.

Summary: This study presents a simple and direct strategy to stabilize mono-P-ligated Pd complex by modulating the electronic properties of the aryl pendant groups in the polymer platform via Pd-arene interactions. The polystyrene-phosphine hybrid demonstrated high catalytic durability for the cross-coupling of chloroarenes under continuous-flow conditions, as confirmed by NMR, TEM, and comparative catalytic studies.

Summary: The synthesis and properties of fluorenyl complexes of cerium were reported, including one, two, and three different fluorenyl ligand complexes. Different reaction conditions were explored to study the structural changes of these cerium complexes with fluorenyl ligands. It was found that Sigma-bond metathesis is the main reaction path for C-C bond formation in fluorenyl cerium complexes.

Summary: In this article, a novel catalytic reaction using Pd(0) and Bronsted acid is reported for the synthesis of biologically important imidazolidinone-fused N-heterocycles through redox-neutral intramolecular N-allylation of indoles and pyrroles with alkynes. This atom-economical method is applicable to a wide range of substrates and eliminates the need for leaving groups or oxidizing agents commonly used in traditional allylation reactions.

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.
