A bridge connects and efficiently transfers the chirality from the backbone of a N‐heterocyclic carbene (NHC) to the metal center. The result is excellent enantioselectivities in the ruthenium‐catalyzed, asymmetric ring‐opening cross‐metathesis of norbornenes with allyltrimethylsilane (see scheme).
