Abstract

original image

Metallacycloaddition: Eine neuartige formale [4+2]-Cycloaddition läuft ab, wenn das Osmiumhydrido(alkenylcarbin) 1 mit Acetonitril umgesetzt wird. Der in hoher Ausbeute gebildete erste Metallapyridiniumkomplex 2 (siehe Schema) liefert beim Deprotonieren die erste Osmapyridinverbindung 3. Durch Behandeln von 3 mit HBF4 kann 2 nahezu quantitativ zurückgebildet werden.
