    Description / Table of Contents: Zusammenfassung Mit Hilfe des Enzymimmunoassay (EMIT-dau-Syva) lassen sich Cannabinoide in Blut und Urin nach inhalativer (10 mg THC) oder oraler (30 mg THC) Aufnahme nachweisen. Die Kurvenverläufe werden mitgeteilt. Im Urin waren erhöhte Spiegel bis zu einer Woche nachweisbar. Eine Absicherung der EMIT-Befunde ist mittels Dünnschichtchromatographie nach absorptiver Anreicherung an einer C18-Extraktionssäule möglich. Nachweisgrenze ist 10 ng THC-Carbonsäure/ml bei Einsatz von 10 ml Urin.
    Notes: Summary The EMIT cannabinoid assay was used for screening blood and urine after smoking tetrahydrocannabinol (THC; 10 mg) or ingestion of THC (30 mg). Cannabinoid levels in urine remain detectable up to 1 week. Confirmation was done by adsorption of the THC carboxylic acid onto a C18 extraction column and elution with acetone and TLC. The method is simple and sensitive and is applicable with common laboratory equipment. The detection limit is 10 ng/ml, using 10 ml urine.

    Description / Table of Contents: Contributions to the Chemistry of Phosphorus. 144. Synthesis and Properties of the Hexaphospha-3-germaspiro[2.4]heptane (t-BuP)2Ge(t-BuP)4The cyclocondensation of K(t-Bu)P—P(t-Bu)K with germanium tetrachloride in the molar ratio of 2:1 yields the novel spirocyclic compound 1,2,4,5,6,7-hexa-tert-butyl-1,2,4,5,6,7-hexaphospha-3-germaspiro[2.4]heptane, (t-BuP)2Ge(t-BuP)4 (1). Besides considerable amounts of (t-BuP)4 are formed and occasionally some (t-BuP)3 can be found. 1 could be isolated in the pure state and has been NMR-spectroscopically characterized as a spirocyclic compound with a P2GeP4 skeleton.
    Notes: Bei der Cyclokondensation von K(t-Bu)P—P(t-Bu)K mit Germaniumtetrachlorid im Molverhältnis 2:1 wird die neue Spiroverbindung 1,2,4,5,6,7-Hexa-tert-butyl-1,2,4,5,6,7-hexaphospha-3-germaspiro[2.4]heptan, (t-BuP)2Ge(t-BuP)4 (1), gebildet. Daneben entstehen beträchtliche Mengen an (t-BuP)4 sowie gelegentlich etwas (t-BuP)3. Verbindung 1 konnte in reiner Form isoliert und kernresonanzspektroskopisch als Spirocyclus mit P2GeP4-Ringgerüst charkterisiert werden.
