An unprecedented, bridged dihydrogen complex of a cofacial metallodiporphyrin and its relevance to the bimolecular reductive elimination of hydrogen
Abstract
Recently, we characterized the first metalloporphyrin dihydrogen complex, Os(OEP)(H₂), and proposed that a similar ruthenium porphyrin dihydrogen complex, Ru(OEP)(H₂), is involved as an intermediate in the catalytic H/D isotopic exchange between water and hydrogen. We now report that treatment of a metal-metal-bonded cofacial ruthenium porphyrin dimer with a sterically bulky ligand in the presence of hydrogen gas has yielded the first known complex containing a dihydrogen ligand bound between two metals. Such a bridged dihydrogen complex is proposed as an intermediate in the bimolecular elimination of dihydrogen from two metalloporphyrin hydrides.
