Synthesis, Structure, and Reactivity of Rhodium Bipyridine Compounds: Formation of a Rh II Hydrido Cluster and a Rh III Peroxido Complex
Treatment of [Rh(μ‐Cl)(coe) 2 ] 2 (coe = cyclooctene) with 4,4′‐di‐ tert ‐butyl‐2,2′‐bipyridine (tbbpy) gives the bipyridine complex [Rh(Cl)(tbbpy)(coe)] ( 1 ). A subsequent reaction with dihydrogen results in the formation of the cluster [{Rh(Cl)(H)(tbbpy)}] 4 ( 2 ). The reaction of [Rh(μ‐Cl)(coe)...
