Synthetic [NiFe] models with a fluxional CO ligand

摘要

A [NiFe] complex [(dppe) Ni(pdt) FeCp*(CO)](+) was isolated and characterized as two isomers [1(CO)](+) and [1 '(CO)](+). Heating the solution of [1(CO)](+) allowed it to convert into [1 '(CO)](+). The oneelectron oxidation of [1 '(CO)](+) to [1 '(CO)] (2+) induced fluxional CO movement providing [1(CO)] (2+). Recovery of [1(CO)](+) was realized by the one- electron reduction of [1(CO)] (2+).
