Donor Acceptor Complexes between the Chalcogen Fluorides SF 2 , SeF 2 , SeF 4 and TeF 4 and an N‐Heterocyclic Carbene
The majority of binary chalcogen fluorides are fiercely reactive and extremely difficult to handle. Here, we show that access to crystalline donor‐acceptor complexes between chalcogen difluorides (sulfur, selenium) and tetrafluorides (selenium, tellurium) with the N‐heterocyclic carbene (NHC) 1,3‐bi...

Zusammenfassung: | The majority of binary chalcogen fluorides are fiercely reactive and extremely difficult to handle. Here, we show that access to crystalline donor‐acceptor complexes between chalcogen difluorides (sulfur, selenium) and tetrafluorides (selenium, tellurium) with the N‐heterocyclic carbene (NHC) 1,3‐bis(2,6‐diisopropylphenyl)imidazol‐2‐ylidene (IPr) is possible conveniently and safely without the need to generate the highly unstable EF
