Perfluoroalkyl substances (PFAS) are now pervasive in the environment. The largest single use material within the PFAS compound class is poly(tetrafluoro)ethylene) (PTFE), a robust and chemically resistant polymer. Despite their widespread use and se

In this mini-review, we summarise the current examples of carbon chain production from metal formyl intermediates with homogeneous metal complexes. To date, the formation of both unsaturated and saturated C2 motifs along with cyclic C3 products has b

The activation of C–C sigma-bonds within strained three- and four-membered hydrocarbons at electrophilic Mg and Zn centres is reported. This was achieved in a two-step process involving (i) hydrometallation of a methylidene cycloalkane followed by

Dynamic covalent chemistry (DCC) plays a critical role in the preparation of extended polymeric materials such as covalent-organic frameworks (COFs). Using DCC, the formation of targeted equilibrium, rather than kinetic, products are driven by the er

Investigations into the reactivity, properties, and applications of osmium(IV) tetraaryl complexes have been hampered by their low yielding syntheses from volatile and toxic OsO4 (typically ≤34%). Here we show that air-stable M(aryl)4 compounds (M

Air-stable, redox-active osmium(IV) tetraaryl complexes can be prepared in yields ≤76% from the novel precursor (Oct4N)2[OsBr6], facilitating the synthesis of Os(mesityl)4 for the first time. This complex exhibits a distorted tetrahedral geometry a
