The inverse sandwich complex [(K(18-crown-6))2Cp][CpFe(CO)2] – unpredictable redox reactions of [CpFe(CO)2]I with the silanides Na[SiRtBu2] (R = Me, tBu) and the isoelectronic phosphanyl borohydride K[PtBu2BH3]†
Abstract
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
