p-Quinone dioxime, a rubber vulcanization accelerator, was selected for bioassay by the National Cancer Institute because of a lack of adequate carcinogenicity data. A bioassay for the possible carcinogenicity of p-quinone dioxime was conducted using Fischer 344 rats and B6C3F1 mice. p-Quinone dioxime was administered in the feed, at either of two concentrations, to groups of 50 male and 50 fem...

An unusual [Mn(IV)Gd(III)(2)(mu(3)-O(2-))](8+) triangular complex has been prepared from the initial use of 2,6-diacetylpyridine dioxime (dapdoH(2)) in 3d/4f cluster chemistry. The complex has an S = (13)/(2) ground state, with exchange parameters J = +0.49 cm(-1) and J' = -0.12 cm(-1) [H = -2J(S(i) x S(j)) convention] for the Gd(III)...Mn(IV) and Gd(III)...Gd(III) interactions, respectively. T...

o-Phthalonitrile couples with chelating dioxime on nickel(II), with formation of a dinuclear nickel(II) macrocyclic complex--the first representative of a new class of imine-appended macrocycles.

Falconensones A and B are new type of yellow pigment isolated from the mycelial extract of ascomycetous fungi, Emericella falconensis. To date, these falconensones and their derivatives, falconensone A p-bromophenylhydrazone and falconensone A dioxime are known to exhibit biological activities, which include growth inhibition and both induction of differentiation and apoptosis of HL60 human leu...

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.

In the title compound, [Cu(C(2)H(5)N(4)O(2))(2)(CH(3)OH)(2)]·2C(2)H(6)N(4)O(2)·2CH(3)OH, the Cu(II) atom, lying on an inversion center, is coordinated by four N atoms from two 1,2-diamino-2-hy-droxy-imino-ethanone oximate anion and two O atoms from two methanol mol-ecules in a distorted octa-hedral geometry. The two uncoordinating oxamide dioxime mol-ecules, each lying on an inversion center, a...

Dioxime oxalates are useful precursors for the clean generation of iminyl radicals by sensitised UV photolysis and can be adapted for serviceable preparations of 3,4-dihydro-2H-pyrroles and phenanthridines.

In the title compound, (C(6)H(16)N)[Ni(C(9)H(4)N(2)O(3))(C(9)H(5)N(2)O(3))], the Ni(II)ion is four-coordinated by two N atoms and two O atoms from two indane-1,2,3-trione-1,2-dioxime ligands. The two organic ligands are linked by an intra-molecular O-H⋯O hydrogen bond. In the crystal, mol-ecules are linked by N-H⋯O hydrogen-bonds.
