It's getting crowded! The synthesis of a new subfamily of imidazolium cations with exceptionally spatially demanding substitution patterns (see scheme) paved the way to reconcile two antagonising effects: steric hindrance and innately high donating ability/basicity in the peralkylated imidazol-2-ylidene ligands/uncharged bases.
