Summary: A novel ratiometric fluorescence probe based on nitrogen-doped blue carbon dots (NCDs) and red gold nanoclusters (Au NCs) was developed for the detection of mercuric ion (Hg2+). A user-friendly fluorescent test paper sensor combined with a smartphone was fabricated for rapid visual and quantitative detection. The probe's ability to selectively bind with Hg2+ on the surface of Au NCs allows for the quenching of red fluorescence while the blue fluorescence of the NCDs remains unchanged, enabling accurate and efficient detection of Hg2+.

Summary: A highly selective ratiometric fluorescent chemodosimeter was synthesized for the detection of Hg2+, which showed remarkable detection properties including high selectivity and sensitivity, large fluorescent signal changes, and well-operation in aqueous solutions. The displacement reaction between phenylboronic acid and Hg2+ ions provided a covalent adduct of mercury ion, leading to significant fluorescent signal changes when aggregated in aqueous solution. With a low detection limit of 15.2 nM, nanomolar concentrations of Hg2+ could be successfully detected, providing a ratiometric fluorescent detection method for quantifying low levels of Hg2+ in groundwater and tap water samples.

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.
