Application of a fluoroiodine analogue of the Togni reagent was studied in fluorocyclization reactions. In the presence of a transition-metal catalyst the applied fluoroiodine reagent can be used for aminofluorination, oxyfluorination, and carbofluorination reactions. The described procedure has a very broad synthetic scope for preparation of functionalized hetero- and isocyclic compounds havin...

The efficacy of iron(II) sulfide (FeS)-based autotrophic denitrification in simultaneous nitrogen and phosphorus removal from wastewater was studied with batch experiments. It was efficient at a wide pH range of 5-9, and temperature range of 10-40 °C. The concentrations of NH₄⁺-N, Mg²⁺ and HCO₃⁻ in the wastewater should be kept over 7.8, 0.24 and 30 mg L⁻¹ for efficient nitrate (NO₃⁻-N) reducti...

It is a pleasure to introduce the 3rd in the series of Thematic Issues on organo-fluorine chemistry for the Beilstein Journal of Organic Chemistry (BJOC). These series have become progressively more successful over time in terms of the number and quality of the contributions received. It is also pleasing to note that the profile and impact factor of the journal has increased steadily over this ...

We report on a first-principles study of the troilite phase of iron sulfide (FeS). We show that even if, a few decades ago, this material was thought to be ferroelectric, the structural transition from the high P6_{3}/mmc to the low P6[over ¯]2c symmetry phase does not involve polar instabilities, though the space inversion center symmetry is broken. Our calculations and symmetry analysis never...
