(Carbon dioxide)bis(trialkylphosphine)nickel complexes
Abstract
The reaction of [NiL4](L = PEt3 or PBun3) with CO2 in toluene affords complexes of formula [Ni(CO2)L2], via the [Ni(CO2)L3] species. The reaction of [Ni(CO2){P(C6H11)3}2]·0.75C6H5Me with O2 to give (peroxocarbonato)-bis( tricyclohexylphosphine)nickel(II) is also reported.
