Reactive metal–ligand (M–L) multiply bonded complexes are ubiquitous intermediates in both synthetic and biological redox catalysis. Mid-to-late M–L multiply bonded complexes are typically reactive and represent attractive intermediates in catalysis, for example in the oxidative functionalization of C–H bonds. M–L multiply bonded complexes that are sufficiently reactive to functionalize C–H bonds are challenging to structurally characterize because oxidative decomposition pathways are facile. Similarly, the facility of intramoleular oxidative decomposition pathways renders harnessing the reactivity of M–L multiply bonded complexes for intermolecular group transfer chemistry a challenge. While synthetic tuning of the ancillary ligand field can stabilize M–L multiply bonded complexes and result in isolable complexes, these efforts inevitably attenuate the reactivity of the M–L multiple bond. Here, we present our efforts to utilize lattice-confinement both to directly characterize reactive M–L multiply bonded complexes and to utilize those structures for synthetically valuable intermolecular C–H functionalization chemistry.<br/>
