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) 2 ] 2 with tbbpy in thf followed by the addition of CN t Bu affords [Rh(Cl)(tbbpy)(CN t Bu)] ( 3 ). The latter reacts with O 2 or 18 O 2 to yield the peroxido complexes [Rh(Cl)(O 2 )(tbbpy)(CN t Bu)] ( 4a ) and [Rh(Cl)( 18 O 2 )(tbbpy)‐(CN t Bu)] ( 4b ), respectively. Complexes 1 – 4 were characterized by X‐ray crystallography. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
