Abstract

Reactions of the Collman reagent, Na-2 [Fe(CO)(4)] center dot 1.5 dioxane, towards the nitrosyl carbonyls [CoNO(CO)(3)] and [Fe(NO)(2)(CO)(2)] in THF as the solvent at room temperature were investigated. Thereby a quick transfer of one nitrosyl ligand from the nitrosyl carbonyl molecule to the iron carbonyl metalate was observed. The reaction with the cobalt compound afforded in high yields the well-known species [Co(CO)(4)](-) and [FeNO(CO)(3)](-) isolated by addition of two equivalents of [PPN](+) Cl- ([PPN](+) = bis(triphenylphosphane) iminium cation) and characterized by their known IR spectra, by elemental analysis and their characteristic colors and melting points. In the reaction of the Collman reagent with [Fe(NO)(2)(CO)(2)] a clean transformation to the tricarbonylnitrosylferrate(1-) as the only formed product was observed.
