“…In recent years, interest in the reactivity of tetrahalodiboranes(4) has almost exclusively come from our laboratories and from the group of Kinjo, where B 2 Br 4 has been used for the construction of molecules with boron–boron multiple bonds such as diborenes and diborynes, as well as precursors to bis(boratabenzene) ligands . We have recently broadened our interests in tetrahalodiboranes(4), developing simple solution‐phase techniques to prepare the remaining B 2 X 4 species (i.e.…”

“…Das Interesse an der Reaktivität von Dibortetrahalogeniden entstammte in den letzten Jahren fast ausschließlich dieser Gruppe und der um Kinjo, wobei B 2 Br 4 einerseits als Baustein zur Konstruktion von Molekülen mit Bor‐Bor‐Mehrfachbindungen wie Diborenen und Diborinen, aber auch als Vorstufe für Bis(boratabenzol)‐Liganden diente . Seitdem erweiterten wir unsere Studien zu Dibortetrahalogeniden mit der Entwicklung einfacher, nasschemischer Methoden zur Darstellung der übrigen B 2 X 4 ‐Spezies (X=F, Cl, I) ausgehend von B 2 Br 4 .…”

“…In beiden Spektren wird eine breite Resonanz bei δ=−16 ppm (Halbwertsbreite: 2940 Hz) detektiert, was im Vergleich zu der im 11 B‐NMR‐Spektrum in Lösung gefundenen Resonanz (δ=70 ppm) deutlich zu höherem Feld verschoben ist und darauf hindeutet, dass die Borzentren der Verbindung in festem Zustand quaternisiert vorliegen. Diese Vermutung wird durch einen Vergleich der chemischen Verschiebung mit 11 B‐NMR‐Resonanzen gelöster Lewis‐Basen‐Addukte [B 2 I 4 (SMe 2 ) 2 ] (δ=−20 ppm), [B 2 I 4 (PMe 3 ) 2 ] (δ=−27 ppm) und [B 2 I 4 (PCy 3 ) 2 ] (δ=−27 ppm) gestützt. Einige weitere im 11 B‐RSHE/MAS‐NMR‐Spektrum detektierte scharfe Signale können flüssigem B 2 I 4 (δ=70 ppm), flüssigem BI 3 (δ=−5 ppm) und weiteren flüssigen Zersetzungsprodukten (δ=56 und 19 ppm) zugeordnet werden (siehe Hintergrundinformationen).…”

“…In recent years, interest in the condensed-phase reactivity of tetrahalodiboranes(4) has come almost exclusively from our laboratories, where B 2 Br 4 is used as a precursor for Lewis base adducts and the construction of boron-boron multiple bonds (B, Figure 1), 1a,b,f,10 as well as precursors to bis(boratabenzene) ligands in transition metal complexes (C, Figure 1). 11 Beyond these applications, however, tetrahalodiboranes(4) offer a near-unlimited number of intriguing possibilities in organic, main-group, transitionmetal, and materials chemistry that we have only begun to explore. The hesitance of the scientific community to adopt these versatile reagents clearly stems from their synthetic routes, which are tedious, temperamental, and require special apparatus in some cases.…”
