Around the world in electrochemistry: a review of the electrochemistry curriculum in high schools.

Electrochemistry education of future researchers and citizens is crucial if we are to decarbonise economies and reach targets for net zero. In this paper, we take an overview of electrochemistry within school education. We used curriculum documents obtained from national and state education department websites and from local teachers, examples of assessments and insights from the chemistry education literature to evaluate the extent of electrochemistry education around the world. We found that there is a great deal of electrochemistry included in the intended curriculum for high schools although there is variability depending on how early students are able to specialise in a smaller number of subjects. A range of contexts are used to illustrate the key ideas including galvanic and electrolytic cells, electrolysis and analysis. There is generally constructive alignment between assessment items and the intended curriculum although in some cases assessment was more simplistic than the intended curriculum would suggest. The effectiveness of the taught curriculum is undermined by low teacher confidence in teaching electrochemistry especially more advanced concepts. Additionally, there are a number of misconceptions generated when students learn electrochemistry with some of these potentially arising from published resources such as textbooks.

Solid phase approaches to N-heterocycles using a sulfur linker cleaved by SmI2.

A sulfur HASC (alpha-hetero-atom substituted carbonyl) linker has been utilized in solid-phase approaches to oxindoles and tetrahydroquinolones. The route to oxindoles employs the first Pummerer cyclizations on solid phase, whereas the route to tetrahydroquinolones involves a microwave-assisted Heck reaction followed by a Michael cyclization. In both cases, the linker is cleaved in a traceless fashion by electron transfer from samarium(II) iodide. The routes illustrate the compatibility of the linker system with a number of reaction types and its utility for library synthesis.

Solid-phase approach to tetrahydroquinolones using a sulfur linker cleaved by SmI2.

[reaction: see text] A sulfur alpha-heteroatom-substituted carbonyl (HASC) linker has been utilized in a solid-phase approach to tetrahydroquinolones. The route illustrates the compatibility of the linker system with palladium-catalyzed transformations and its utility for library synthesis. The linker is cleaved by electron transfer from samarium(II) iodide.
