Abstract

Abstract Translated from German Seltenerdmetall-Alkoxide hoher Löslichkeit und Flüchtigkeit zeichnen sich durch Liganden OR mit Donorfunktionalitäten aus. Die Liganden bilden - unter Einschluß des zentralen Seltenerdmetallatoms - einen fünf- oder sechsteiligen Ring, der das Metallatom, ein benachbartes Sauerstoffatom, zwei oder drei Kohlenstoffatome und ein Donoratom (N oder O) umfaßt, wobei die organischen Reste überwiegend H-Atome, Methyl-, Ethyl-, Isopropyl- oder tert.-Butylgruppen sein können. Rare earth metal alkoxides with high solubility and volatility are characterized by ligands OR with donor functionalities. The ligands - including the central rare earth metal atom - form a five- or six-part ring which comprises the metal atom, a neighboring oxygen atom, two or three carbon atoms and a donor atom (N or O), the organic radicals predominantly H atoms, methyl , Ethyl, isopropyl or tert-butyl groups.
