We present an accessible implementation of augmented reality projections for the depiction of complex structures and motifs, including atomic orbitals and elemental allotropes. The utilization of a free, crossplatform-compatible, online database of these structures provides the access route for closer examination, either via augmented reality or an online interface. Both will facilitate an enhanced understanding of the complex structures and can be applied in taught courses as well as during the self-study of students.

A facile one‐pot gram‐scale synthesis of tetraalkylammonium tetrafluoridochlorate(III) [cat][ClF4] ([cat]=[NEt3Me]+, [NEt4]+) is described. An acetonitrile solution of the corresponding alkylammonium chloride salt is fluorinated with diluted fluorine at low temperatures. The reaction proceeds via the [ClF2]− anion which is structurally characterized for the first time. The potential application of [ClF4]− salts as fluorinating agents is evaluated by the reaction with diphenyl disulfide, Ph2S2, to pentafluorosulfanyl benzene, PhSF5. The CN moieties in acetonitrile and [B(CN)4]− are transferred in CF3 groups. Exposure of carbon monoxide, CO, leads to the formation of carbonyl fluoride, COF2, and elemental gold is dissolved under the formation of tetrafluoridoaurate [AuF4]−.

Trifluoromethoxylated (hetero)arenes are of great interest for several disciplines, especially in agro‐ and medicinal chemistry. Radical C−H trifluoromethoxylation of (hetero)arenes represents an attractive approach to prepare such compounds, but the high cost and low atom economy of existing .OCF3 radical sources make them unsuitable for the large‐scale synthesis of trifluoromethoxylated building blocks. Herein, we introduce bis(trifluoromethyl)peroxide (BTMP, CF3OOCF3) as a practical and efficient trifluoromethoxylating reagent that is easily accessible from inexpensive bulk chemicals. Using either visible light photoredox or TEMPO catalysis, trifluoromethoxylated arenes could be prepared in good yields under mild conditions directly from unactivated aromatics. Moreover, TEMPO catalysis allowed for the one‐step synthesis of valuable pyridine derivatives, which have been previously prepared via multi‐step approaches.

Es wird über eine einfache Eintopfsynthese für Tetraalkylammoniumtetrafluoridochlorat(III), [kat][ClF4] ([kat]=[NEt3Me]+, [NEt4]+), im Gramm‐Maßstab berichtet. In Acetonitril wird ein Chloridsalz bei tiefen Temperaturen mit verdünntem Fluor umgesetzt. Das Zwischenprodukt dieser Reaktion, [ClF2]−, wird zum ersten Mal strukturell charakterisiert. Mögliche Anwendungen des [ClF4]−‐Salzes werden durch folgende Reaktionen eruiert: Diphenyldisulfid, Ph2S2, wird in Pentafluorsulfanylbenzol, PhSF5, überführt, sowie die CN‐Gruppen in Acetonitril und in Tetracyanoborat ([B(CN)4]−) in CF3‐Gruppen. Eine Reaktion mit Kohlenstoffmonoxid, CO, führt zu Fluorphosgen, COF2. Elementares Gold löst sich unter Bildung des Tetrafluoridoaurates, [AuF4]−.

We present a facile synthesis of the soluble fluoridobromates [NEt3Me][BrF4] and [NEt3Me][Br2F7] via fluorination of the corresponding bromide salts in acetonitrile, propionitrile or bromine. We structurally characterized the [BrF2]– anion, an intermediate during the synthesis, for the first time. Additionally, the dissolution of noble metals to form the corresponding halometallates as well as the application of [NEt3Me][BrF4] as a fluorination agent for disulfides to form pentafluorosulfanyls was studied.
