Preparation and Characterization of a Halogen-Bonded Shape-Persistent Chiral Alleno-acetylenic Inclusion Complex
A chiral bidentate inclusion complex has been formed by halogen-bond interaction between the pyridyl moieties of a pyridoallenoacetylenic host and octafluorodiiodobutane. X-ray crystallography showed that the guest adopts a chiral conformation inside the molecular channels formed by stacking of the...

| Zusammenfassung: | A chiral bidentate inclusion complex has been formed by halogen-bond interaction between the pyridyl moieties of a pyridoallenoacetylenic host and octafluorodiiodobutane. X-ray crystallography showed that the guest adopts a chiral conformation inside the molecular channels formed by stacking of the host units. A 10 ppm shielding of the 15N NMR resonance for the pyridil units provided evidence of the formation of the halogen-bond complex in solution. |
