Redox Activation of Alkene Ligands in Platinum Complexes with Non-innocent Ligands

Redox activation of alkene ligands in platinum complexes with non-innocent ligands.

The reactivity of metal olefin complexes with non-innocent ligands (NILs) was examined. Treatment of PtCl(2)(diene) with the deprotonated catechol or aminophenol ligands afforded the corresponding Pt(NIL)(diene) complexes. The Pt((t)BA(F)Ph)(COD), Pt((t)BA(F)Ph)(nbd), and Pt(O(2)C(6)H(2)(t)Bu(2))(COD) (H(2)(t)BA(F)Ph = 2-(2-trifluoromethyl)anilino-4,6-di-tert-butylphenol, H(2)O(2)C(6)H(2)(t)Bu(...

Dioxygen activation by mixed-valent dirhodium complexes of redox non-innocent azoaromatic ligands.

The isolation, structural chracterisation and electronic structure of a formally mixed-valent Rh(-I)-Rh(III) complex is described, along with its reaction with dioxygen leading to double arene hydroxylation of the coordinated ligands.

Non-innocent ligands.

Artificial Hydrogenases : Utilization of Redox Non - Innocent Ligands in Iron Complexes for Hydrogen Production

Here we report the synthesis and characterization of functional models of hydrogenases for electrocatalytic prouduction of hydrogen from weak acids. The complexes employ iron in bio-inspired coordination environments yielding catalysts that are fast and require very little electrochemical overpotential to support turnover.
