CO oxidation at nickel centres by N2O or O2 to yield a novel hexanuclear carbonate†
Abstract
Reaction of a nickel(0) carbonyl complex, K2[LtBuNiCO]2, with N2O generates a cyclic carbonate compound composed of six [NiII(CO3)K]+ units. The same product can also be obtained using O2 as the oxidant in a solid-state/gas reaction. These conversions represent unique examples of a nickel-bound CO oxidation by N2O and O2, respectively.
