Oxime carbonates were found to be excellent precursors for the clean and direct generation of iminyl radicals under UV irradiation. Suitably functionalised iminyls underwent cyclisations yielding various phenanthridines and also substituted quinolines and isoquinolines. EPR and X-ray analyses of oxime carbonates provided insight into the mechanism.

The use of phenyl-2-pyridyl ketone oxime and di-2-pyridyl ketone oxime in Mn chemistry has led to hexanuclear clusters with unprecedented (Mn(II)(4)Mn(III)Mn(IV)) or extremely rare (Mn(II)Mn(III)(5) and Mn(II)(3)Mn(III)(3)) metal oxidation-state combinations and uncommon structural motifs.

In the title compound, C(9)H(11)NO(3), the oxime grouping is twisted by 12.68 (6)° with respect to the dimethoxyl-benzene ring. In the crystal, mol-ecules are linked into an infinite [100] chain via O-H⋯N hydrogen bonds, instead of the more common oxime packing motif of dimers with an R(2) (2)(6) graph-set motif.

Carbon nanotube electrodes were modified with ferrocene and laccase using two different click reactions strategies taking advantage of bifunctional dendrimers cyclopeptides. Using diazonium functionalization the efficiency oxime ligation, combination both multiwalled carbon surfaces or cyclopeptides allows access to a high surface coverage in order 50 nmol cm–2, 50-fold increase compared classi...

In the title compound, C(13)H(11)ClN(2)O(3), the nine-membered bicycle includes an oxime group having the C=N group in an E configuration. The isoxazole ring is almost planar [r.m.s. deviation = 0.0056 Å]; the dihedral angle between the isoxazole and 4-chloro-phenyl ring is 75.60 (5)°. In the crystal, inter-molecular O-H⋯N(isoxazole) hydrogen bonds give rise to chains running along the b axis.

The biosynthesis of the tyrosine-derived cyanogenic glucoside dhurrin involves N-hydroxytyrosine, (E)- and (Z)-p-hydroxyphenylacetaldehyde oxime, p-hydroxyphenylacetonitrile, and p-hydroxymandelonitrile as intermediates and has been studied in vitro using a microsomal enzyme system obtained from etiolated sorghum (Sorghum bicolor [L.] Moench) seedlings. The biosynthesis is inhibited by carbon m...

In the title compound, [Ni(HCOO)(2)(C(7)H(8)N(2)O)(2)], the Ni atom is six-coordinated by four N atoms from two oxime ligands and by two O atoms from two formate ions in a distorted octa-hedral geometry, with the oxime-N atoms mutually trans. The mol-ecular conformation is stabilized by intra-molecular O-H⋯O hydrogen bonds.

The title compound, C(6)H(6)N(2)O(2), was obtained as a product of an in vitro study of the metabolism of benzofuroxan. The molecule exhibits a amphi configuration of the oxime groups C=N-OH. One oxime group is involved in the formation of a strong intra-molecular O-H⋯N hydrogen bond, while another links mol-ecules into zigzag chains along the c axis via inter-molecular O-H⋯N hydrogen bonds.
