Abstract: | Contributions to the Chemistry of Organo-Transition Metal Compounds. 47. Reactions of Hexachlorocerates(IV) with Organolithium Compounds Pyridinium hexachlorocerate(IV) reacts with lithium organyls RLi RLi (R = 1-Nor, (CH3)2NCH2CH2CH2, n-C4H9) in the molar ratio 1:2 with formation of Li2[CeCl6] · 2 NC5H5. A further mol RLi effects a reduction to Li3[CeCl6] · 2 NC5H5. With an excess of RLi amidocerium(III) complexes of the typ Li4 are formed. Li2[CeCl6] is formed also at reactions of quartery ammonium salts, e. g. [C6H5CH2N(C2H5)3]2[CeCl6], with RLi (R = 1-Nor, Me22NCH2CH2CH2) followed by an reduction to Li3[CeCl6]. An excess of the lithium organyl effects the formation Li4[RCeCl6] complexes. The yielded compounds were characterized by elementary analysis, the hydrolysis and deuterolysis products, magnetic moments, and IR-spectra. |
