Relative tolerance and expression of resistance to phosphine in life stages of the rusty grain beetle, Cryptolestes ferrugineus [PDF]
Cryptolestes ferrugineus is a serious cosmopolitan pest of stored products. Frequent and indiscriminate usage of phosphine has caused the development of high levels of resistance to this fumigant.

Multicomponent Synthesis of Fluorine‐Containing Bioactive Compounds and Drugs
Multicomponent reactions are robust synthetic tools to assamble complex polyheterocycles and other interesting molecular architectures with potential application in medicinal chemistry, including their fluorine‐containing analogues. Fluorine atoms placed strategically into bioactive molecules often enhance essential pharmacokinetic parameters like ...

The Crystal Structure of Anhydrous [NMe4]F
The crystal structure of tetramethylammonium fluoride, [NMe4]F, commonly used as a source for “naked” fluoride ions, is determined based on powder X‐ray diffraction data. In the crystal structure, the F− ions are tetrahedrally surrounded by four [NMe4]+ ions and vice versa, resulting in a wurtzite type of structure.

Click Chemistry‐Enabled Synthesis of Diversely Functionalized Cyclobutenes
This work expands the synthetic scope of a [2 + 2] click chemistry cycloaddition between ethene‐1,1‐disulfonyl fluoride (EDSF) and a diverse library of alkynes to access 29 highly functionalized cyclobutenes. Substrate variation, including electron‐withdrawing and electron‐donating groups, enables precise regiocontrol.

Flat grain beetle fumigation protocol [PDF]
Flat grain beetle (FGB) is a major emergency plant pest (EPP) of stored grain in Australia. Populations of FGB have recently developed high level resistance to phosphine (the only viable fumigant available for non-quarantine use) resulting in control ...

Tidying away gases and anions. The complementary storage & in‐solution release of tetrafluoride (SOF4), sulfuryl fluoride (SO2F2) and pentafluorooxosulfate (OSF5) anions was achieved. This was performed using fluorosulfonyl pentafluorooxosulfate (FSO2‐OSF5) a stable, high boiling liquid, obtained from SO2 and the pentafluorosulfur hypofluorite (FOSF5 ...
