    Description / Table of Contents: Contributions to the Chemistry of Transition Metal Alkyl Compounds. 50. A non-common Organolanthanum CompoundLanthanum reacts with dibenzyl mercury in tetrahydrofuran as a solvent with splitting of solvent molecules and with formation of ethylene and a benzyl hydrido vinyloxide lanthanum complex of the composition C6H5CH2La(H)OCH=CH2 · 2 THF. This complex, primary well soluble in tetrahydrofuran, is extremely sensitive against air and moisture and undergoes a fast coordination polymerisation with a strong decrease of the solubility.The compound was characterized by elementary analysis, the hydrolysis and deuterolysis reaction, and by the i.r. spectra.
    Notes: Lanthan reagiert mit Dibenzylquecksilber in Tetrahydrofuran als Reaktionsmedium unter Spaltung von Lösungsmittelmolekülen zu Ethylen und einem Benzylhydridovinyloxid-lanthan-Komplex der Zusammensetzung C6H5CH2La(H)OCH=CH2 · 2 THF. Dieser anfangs in Tetrahydrofuran gut lösliche Komplex ist extrem luft- und feuchtigkeitsempfindlich und unterliegt rasch einer Koordinationspolymerisation unter starker Abnahme der Löslichkeit.Die Charakterisierung erfolgte durch Elementaranalyse, Verfolgung der Hydrolyse und Deuterolyse sowie Auswertung des IR-Spektrums.
