We report a novel, inexpensive double thiolation reagent that sulfurizes a broad range of imidazo[1,2-α]pyridines under mild conditions. Importantly, diethylaminosulfur trifluoride, as a common nucleophilic fluorinating reagent, was utilized as a novel thiolation reagent.

Developing advanced adsorbents for selectively deducing mercury (Hg) in water to one billionth level is of great significance for public health and ecological security, but achieving the balance among efficiency, cost and environmental friendliness of adsorbents still faces enormous challenges. Herein, we present a high thiol content non-conjugated nano polymer network (PVB-SH) through simple microemulsion polymerization for efficient Hg ion (Hg(II)) removal. The PVB-SH is prepared by conventional commercial reagents and does not consume toxic organic solutions.

In this study, we propose a strategy to explore the impact of the proportion of tris(2-carboxyethyl)phosphine (TCEP) and 6-mercaptohexanol (MCH) on the efficiency of oligonucleotide functionalization on PDMS microfluidic channels equipped with pairs of homemade microfabricated platinum microelectrodes. We identified an optimal concentration of these compounds that enables the effective orientation and distribution of probes, thereby facilitating subsequent target hybridization. The experiment included optimizing sample injection into microfluidic channels.

A new fluorescent probe for detecting hydrogen sulfide (HS) was developed through the thiolation reaction of 2-chloro-1,4-naphthoquinone. Rhodol was employed as the fluorophore, while 2-chloro-1,4-naphthoquinone acted as the reactive group for HS. The probe remains non-fluorescent under sunlight but emits a strong fluorescence upon reaction with HS, accompanied by a visible color change in the solution.

Nature chooses a high-valent tungsten center at the active site of the enzyme acetylene hydratase to facilitate acetylene hydration to acetaldehyde. However, the reactions of tungsten-coordinated acetylene are still not well understood, which prevents the development of sustainable bioinspired alkyne hydration catalysts. Here we report the reactivity of two bioinspired tungsten complexes with the acetylene ligand acting as a four-: [W(CO)(CH)(PymS)] () and a two-electron donor: [WO(CH)(PymS)] (), with PMe as a nucleophile to simulate the enzyme's reactivity (PymS = 4-(trifluoromethyl)-6-methylpyrimidine-2-thiolate).

Useful monophosphorus products are obtained from both white and red phosphorus via a simple strategy involving initial oxidation by aryl disulfides followed by quenching with nucleophiles. Direct transformations of elemental phosphorus are usually very challenging, forcing chemists to instead rely on inefficient and hazardous multi-step methods. However, here they are achieved using inexpensive and easy-to-handle reagents, providing access to diverse P-C, P-N and P-O bonded products in good yields.
