Rauchfuss, Thomas B. Linck, Rachel Clare 2015-09-25T22:13:14Z 2015-09-25T22:13:14Z 10000-01-01 2004 2004 The activation of dihydrogen has only been observed indirectly through the photolytically-induced H/D exchange of [Fe2(mu-H)(SR) 2(CO)4(PR3)2]+ Fe-only hydrogenase models with D2. The diphosphine diruthenium complex Ru2(S2C3H6)(CO)4(PCy 3)2 oxidatively adds dihydrogen to produce the dihydride Ru2(S2C3H6)(mu-H)(H)(CO) 3(PCy3)2, the first example of the homolytic activation of dihydrogen by a synthetic Fe-only hydrogenase model. The protonation of the terminal hydride ligand of Ru2(S2C3H 6)(mu-H)(H)(CO)3(PCy3)2 has the potential to produce the first synthetic model of the Fe-only hydrogenase enzyme with a bound dihydrogen ligand. While these models are based on diruthenium systems rather than diiron systems, comparison of the iron-based enzyme to synthetic ruthenium mimics may lead to innovations in the preparation of biologically-inspired catalysts.
