Zur Reaktion aromatischer Phosphanderivate mit Elektronen, I. On the Reaction of Aromatic Phosphane Derivatives with Electrons, I
Die Reduktion aromatischer Phosphane und Phosphanoxide mit Alkalimetallen in Ethern liefert farbige, paramagnetische Lösungen [1]. Die Charakterisierung der Radikale durch Elektronenspinresonanz ist wegen ihrer Reaktivität erschwert: Spaltung einer P-Aryl-Bindung kann zu SekundärRadikalionen mit Phosphor-Metall-Bindung [2, 3] oder zu weiteren Folgeprodukten [4, 5] führen, zur Erzeugung der prim...
متن کاملMagnesium-catalysed nitrile hydroboration
A b-diketiminato n-butylmagnesium complex is presented as a selective precatalyst for the reductive hydroboration of organic nitriles with pinacolborane (HBpin). Stoichiometric reactivity studies indicate that catalytic turnover ensues through the generation of magnesium aldimido, aldimidoborate and borylamido intermediates, which are formed in a sequence of intramolecular nitrile insertion and...
متن کاملComparative metabolism of geranyl nitrile and citronellyl nitrile in mouse, rat, and human hepatocytes.
Geranyl nitrile (GN) and citronellyl nitrile (CN) are fragrance components used in consumer and personal care products. Differences in the clastogenicity of these two terpenes are postulated to result from differential biotransformation, presumably involving the conjugated nitrile moiety. The metabolic clearance and biotransformation of GN and CN were compared in primary hepatocytes from mice, ...
متن کاملNitrile-Degrading Bacteria Isolated from Compost
Nitriles are a diverse group of organic compounds with –C≡N as functional group. Most nitriles are slightly cytotoxic but some cause severe toxic effects. More than 120 naturally occurring nitriles without considering cyanogenic glycosides are present in terrestrial and marine habitats, especially in plant components such as almonds or other fruit pits. The most common group of naturally occurr...
متن کاملPost-translational modifications in nitrile hydratase family
Fe-type nitrile hydratase (NHase) from Rhodococcus sp. N771 has a novel non-heme iron active center with two post-translationally modified cysteine residues, cysteine-sulfenic and -sulfinic acids. The modified residues are involved in the sequence motif, Cys-Xxx-Leu-Cys-Ser-Cys (Xxx = Ser(Fetype)/Thr(Co-type)), which is conserved among all known NHases as well as in the homologous enzyme, thioc...
