Synthese und Untersuchung der Lanthanoidoxidnitrate

The lanthanide oxide nitrates LnONO3 with Ln = Pr, Nd, and Sm-Yb were synthesised by thermal decomposition of hydrated lanthanide nitrates. The compounds were refined isotypically to YONO3 in the tetragonal space group P4/nmm and the structure is closely related to the PbFCl-type. Because of the orientational disorder of NO3− in this structure refinement a possible superstructure is discussed. ...

Spezielle Aspekte der Verlustleistungsgetriebenen High-Level Synthese

Dies ist ein Kapitel. In diesem Vorhaben wurde auf Architekturebene ein Verfahren entwickelt, das es erlaubt aus der Analyse einer bit-seriellen asynchronen Architektur charakteristische Merkmale zur Leistungseinsparung zu extrahieren. Diese Merkmale wurden dann unter Anwendung bestimmter Techniken auf synchrone bit-serielle Architekturen übertragen. Die entwickelten Analysemethoden fließen dir...

SYNTHESIS OF 8-HYDROXY-6-METHOXY- 3-UNDECYLISOCOUMARIN AND 2-HY DROXY - 4-METHOXY-6-(2-OXOTRIDECYL) BENZOIC ACID

Straightforward conversion of (+)-6,8-dimethoxy-3,4-dihydro-3- undecylisocoumarin (3) to the title isocoumarin was carried out. Hydrolytic ring opening of (3) afforded the hydroxy acid (4) which was immediately oxidized to keto acid (5) using chromic acid, Cyclodehydration of (5) afforded the 6,8- dimethoxy-3-undecylisocoumarin (6) which on selective demethylation of 8- methoxy group furni...
