Abstract
Erst zwei tert‐Butylgruppen an den Stickstoffatomen der aus 1 durch Reduktion mit Kalium zugänglichen cyclischen Carbene 2 haben eine Stabilisierung zur Folge, die eine unbegrenzte Lagerung ermöglicht. Sterisch weniger gehinderte Carbene des Typs 2 (R = Me, Et, iPr) dimerisieren hingegen bei Raumtemperatur zu den Olefinen 3. magnified imageKeywords
