The clusters (μ3-RP)Fe3(CO)10 (1) or (μ3-RP)Fe3(CO)9(μ2-H)2 (2) can reversibly be transformed into the cluster anions 3-RP)Fe3(CO)9(μ2-H)>- (3) and 3-RP)Fe3(CO)9>2- (4).The pyrophoric clusters 4 react with the divalent electrophile CH2I2 to give the complexes (μ3-η2-RP=CH2)Fe3(CO)10 (5), which contain a cluster-stabilized phosphaalkene, RP=CH2, as a ligand.With monovalent electrophiles R'X, such as Me2SO4, compound 4 (R = anisyl), yields, upon protolytic work-up, the complexes (μ3-η3-R'P-anisyl)Fe3(CO)9(μ2-H) (6) in which the phosphorus-bound aryl residue of the μ2-bridging phosphide ligand (R'P-anisyl) forms an η2-coordination to the third iron atom of the cluster.The η2-coordination of the aryl substituent may be reversibly released by two-electron ligands L under formation of (μ2-R'P-anisyl)(μ2-H)Fe3(CO)9L (7).In addition, the transformation sequence of 5 into 6 is accomplished by an H-, H+ addition sequence.The experiments are documented by analytic and spectroscopic data as well as by X-ray analyses.
