The dimeric iron carbonyl [CpFe(CO)2]2 and the iodosilanes tBu2RSiI were obtained from the reaction of [CpFe(CO)2]I with the silanides Na[SiRtBu2] (R = Me, tBu) in THF. By the reactions of [CpFe(CO)2]I and Na[SiRtBu2] (R = Me, tBu) the disilanes tBu2RSiSiRtBu2 (R = Me, tBu) were additionally formed using more than one equivalent of the silanide. In this context it should be noted that reduction of [CpFe(CO)2]2 with Na[SitBu3] gives the disilanes tBu3SiSitBu 3 along with the sodium ferrate [(Na(18-crown-6))2Cp] [CpFe(CO)2]. The potassium analogue [(K(18-crown-6)) 2Cp][CpFe(CO)2] (orthorhombic, space group Pmc2 1), however, could be isolated as a minor product from the reaction of [CpFe(CO)2]I with [K(18-crown-6)][PtBu2BH3]. The reaction of [CpFe(CO)2]2 with the potassium benzophenone ketyl radical and subsequent treatment with 18-crown-6 yielded the ferrate [K(18-crown-6)][CpFe(CO)2] in THF at room temperature. The crown ether complex [K(18-crown-6)][CpFe(CO)2] was analyzed using X-ray crystallography (orthorhombic, space group Pna21) and its thermal behaviour was investigated.
