Mercury(II)-mediated formation of imide-Hg-imide complexes.
Three different kinds of cyclic imides with imido protons are chosen to interact with Hg(II): succinimide, the simplest cyclic imide (five-membered ring); phthalimide (conjugated five-membered ring); and 1,8-naphthalimide (conjugated six-membered ring). Based on the results of MS, (1)H-NMR, XPS, IR spectroscopy and fluorescence response analyses, it is suggested that N-unsubstituted cyclic imid...
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 کاملThe imide tautomer of sulfasalazine.
The title compound, 5-[4-[(2-pyridylideneamino)sulfonyl]phenyldiazenyl]salicylic acid, C(18)H(14)N(4)O(5)S, crystallizes as the imide tautomer in the monoclinic space group P2(1)/c. In addition to an intramolecular O-H.O hydrogen bond, intermolecular O-H.O interactions link adjacent molecules into helices, which are connected by pairwise N-H.N interactions into two-dimensional hydrogen-bonded l...
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...
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...
