“…Specifically, it may be that halide dissociation (Cl − or F − ) from PhSeX 3 to generate the active PhSeX 2 + electrophile (where X = Cl or F) is slower when the selenium center carries one or more fluoride ligands. In support of this assertion, it is known that the stoichiometric reaction of cyclohexene with PhSeF 3 is slow, requiring 2–3 h to reach completion, 38 whereas the analogous addition of PhSeCl 3 requires only a few minutes. 26 …”

“…The 19 F NMR signal of the Ritter product 7b (d = À168.9 ppm) corresponds to the exo-oriented fluorine in the norbornane structure [7,11,13,27]. In the 1 H NMR spectrum, the double doublet at 4.99 ppm ( 3 J H,F = 30.…”

“…Bei der Verwendung von Diphenyldiselenid als Substrat konnten wir eine nahezu quantitative Umsetzung zu Aryl‐SeF 3 ( 31 ) beobachten. Verbindungen dieser Klasse sind als Difluorierungsmittel bekannt, wurden jedoch in den letzten 20 Jahren nicht näher untersucht. Ein Grund dafür ist höchstwahrscheinlich, dass die einzige Syntheseroute zu entsprechenden Molekülen auf der Verwendung von stöchiometrischen Mengen von teurem XeF 2 beruht.…”
