- W4243007753 abstract "The reaction of calcium bis[bis(trimethylsilyl)amide] with 6-methyl-6-organylfulvene yields calcium bis(1-organyl-ethen-1-yl-cyclo-pentadienide) with organyl groups such as methyl (1), phenyl (2) and iso-butyl (3). Compound 2 crystallizes in the monoclinic space group P2/n with a = 1266.8(2), b = 1225.6(2), c = 1831.4(2) pm, β = 97.65° and Z = 4. The asymmetric unit contains two half-molecules, both the calcium atoms are coordinated distorted tetrahedrally by two cyclo-pentadienide ligands and two THF molecules. The metathesis reaction of the calcocene 1 with iron(II) chloride leads to the corresponding ferrocene derivative 4 in good yield. Die Reaktion von Calcium-bis[bis(trimethylsilyl)amid] mit 6-Methyl-6-organylfulvenen führt zu den Calcium-bis(1-organyl-ethen-lyl-cyclo-pentadieniden) mit Organylresten wie Methyl (1), Phenyl (2) und iso-Butyl (3). Verbindung 2 kristallisiert in der monoklinen Raumgruppe P2/n mit a = 1266,8(2), b = 1225,6(2), c = 1831,4(2) pm, β = 97,65° und Z = 4. Die asymmetrische Einheit enthält zwei Molekülhälften; die Calciumatome sind verzerrt tetraedrisch von zwei Cyclo-pentadienid- und zwei THF-Liganden umgeben. Die Metathesereaktion des Calcocens 1 mit Eisen(II)chlorid liefert das entsprechende Ferrocen-Derivat 4 in guter Ausbeute." @default.
