| Summary: | The chemical bond between a Lewis-acidic metal and a Brønsted/Lewis-basic sulphur donor provides M-S structures with functional properties that are relevant for a variety of processes such as the heterolytic cleavage of H
. Direct comparison of reactivity properties between molecular M-S structures can be difficult owing to divergent electronic properties of stabilizing ligand scaffolds. This work reports on a mechanistic study of stoichiometric H
oxidation at electronically distinct [Ni
(μ-SR)
]
and [Ni-SR]
structures that derive from the same 1,4-terphenyldithiophenol ligand. In this context, the effect of metal containing side-products such as [HNi(PMe
)
]
on overall H
oxidation reactivity displayed by Ni-S structures has been investigated quantitatively in addition to external parameters such as solvent and H
pressure. |
