“…An extrapolation from the structural features of the N-substituted cations and their reactions discussed above leads to the conclusion that the C−H···X contacts in tropylium ions can also be interpreted as initial phases of the deprotonation (eq 6e). The crystal structures of several iron and platinum complexes of the carbene 157 are known. They are characterized by a σ-bond-like coordination of 157 via the carbene lone pair to the metal center.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
