Mission accomplished : More than 100 years after first attempts at isolating a stable silanone, this task has finally been completed with the isolation of a metallosilanone complex (see Scheme). The elusive bare SiO bond was made accessible by utilizing the coordination sphere of an electron‐rich chromium fragment in combination with a sterically demanding saturated N‐heterocyclic carbene (NHC) to protect the reactive site.
