Dimethyl hydrazine-1,2-dicarboxylate–triphenylphosphine oxide (1/1)
In the crystal structure of the title compound, C(4)H(8)N(2)O(4)·C(18)H(15)OP, two triphenyl-phosphine oxide mol-ecules and two dimethyl hydrazine-1,2-dicarboxyl-ate mol-ecules are connected via N-H⋯O hydrogen bonds of moderate strength and are related via a twofold rotational axis. Weak C(ar)-H⋯ O contacts strengthen the crystal structure.
متن کاملHydrazine-reduction of graphite- and graphene oxide
We prepared hydrazine-reduced materials from both graphite oxide (GO) particles, which were not exfoliated, and completely exfoliated individual graphene oxide platelets, and then analyzed their chemical and structural properties by elemental analysis, XPS, TGA, XRD, and SEM. Both reduced materials showed distinctly different chemical and structural properties from one another. While hydrazine ...
متن کامل12-(2-Methoxyphenyl)-9,9-dimethyl-8,9-dihydro-12H-benzo[a]xanthen-11(10H)-one
The title compound, C(26)H(24)O(3), was synthesized via the coupling of 2-methoxy-benzaldehyde, 2-naphthol and 5,5-dimethyl-cyclo-hexane-1,3-dione. The pyran ring adopts a boat conformation, while the cyclo-hexenone ring is in an envelope conformation. The 2-methoxy-phenyl ring is almost perpendic-ular to the plane through the four C atoms of the pyran ring [dihedral angle = 88.76 (9)°].
متن کامل9,9-Dimethyl-12-phenyl-8,9-dihydro-12H-benzo[a]xanthen-11(10H)-one
The title compound, C(25)H(22)O(2), was synthesized via the three-component coupling of benzaldehyde, 2-naphthol and 5,5-dimethyl-cyclo-hexane-1,3-dione. In the crystal structure, centrosymmetrically related mol-ecules are linked into dimers by pairs of inter-molecular C-H⋯O hydrogen bonds. The dimers are further connected into a three-dimensional network by π-π aromatic stacking inter-actions ...
متن کامل12-(4-Chlorophenyl)-9,9-dimethyl-9,10-dihydro-8H-benzo[a]xanthen-11(12H)-one
The title compound, C(25)H(21)ClO(2), was synthesized via the three-component coupling of 4-chloro-benzaldehyde, 2-naphthol and 5,5-dimethyl-cyclo-hexane-1,3-dione. The pyran ring adopts a boat conformation, while the cyclo-hexenone ring is in an envelope conformation. The 4-chloro-phenyl ring is almost perpendicular to the pyran ring [dihedral angle = 87.39 (1)°]. In the crystal, mol-ecules ar...
