- Abstract:
- ... Although cyanofluoroalkylation has received increasing attention, a toxic cyanation reagent is usually required. Herein, a Cu-catalyzed difluorocarbene-based cyanodifluoromethylation of alkenes with BrCF₂CO₂Et/NH₄HCO₃ under photocatalytic conditions is described. BrCF₂CO₂Et and NH₄HCO₃ serve as a carbon source and a nitrogen source of the nitrile group, respectively, avoiding the use of a stoichio ...

- Abstract:
- ... The redox state of arsenic controls its toxicity and mobility in the subsurface environment. Understanding the redox reactions of arsenic is particularly important for addressing its environmental behavior. Clay minerals are commonly found in soils and sediments, which are an important host for arsenic. However, limited information is known about the redox reactions between arsenic and structural ...

Silicon nanocrystals (SiNCs) have attracted attention due to their unique properties that render them particularly suitable for a high variety of applications, such as electrochemiluminescence (ECL) sensors. However, the electrochemiluminescence of SiNCs has not been investigated in depth so far and the research has been focused on conventional quantum dots composed of toxic or rare materials. Her ...

They have wide octanol-water partition coefficients (Kₒw) and different ionization constants (pKₐ) resulting in a poor analysis accuracy and efficiency. A suitable analytical method is the first prerequisite for further ...

Electrochemical methods are ideally suited to carry out this reduction without added external reductants. Achieving this transformation at low overpotentials requires mediating the transfer of protons and electrons to Cr(vi). In this review thermodynamic parameters will be discussed to understand Cr(v ...
