Metal coordination polymers of 2,3-bisimidazol-1-ylquinoxaline: Syntheses, crystal structures, and luminescent properties

Three new metal-organic coordination polymers, namely, [Zn(mu 2-BiImQuin)(OAc)2]·H2O (1), [Zn(mu2-BiImQuin)2(H2O)2] 2·4Cl·H2O (2), and [Mn(mu2- BiImQuin)2(N3)2]·4H2O (3) were prepared by reaction of the corresponding transition metal salt with new rigid ligand 2,3-bisimidazol-1-ylquinoxaline (L) with diffusion or solution methods (BiImQuin = 2,3-bisimidazol-1-ylquinoxaline). All the complexes were characterized by elemental analysis, IR, TGA, PXRD, and single crystal X-ray diffraction determination. A one-dimensional single chain was observed in complex 1, however one-dimensional bead-like double chains were observed in complexes 2 and 3. In the three complexes, the rigid didentate ligands bridged the metal ions into similar “zigzag” chain, and two “zigzag” chains are arranged into bead-like double chain in complexes 2 and 3, where each metal ion is coordinated with four different didentate BiImQuin rather than two. On the other hand, the anions do great influence on the final supramolecular structure through coordination behavior and hydrogen-bonding interactions. The complexes 1 and 2 display strong room temperature photoluminescence in visible region, which may be assigned to ligand-to-metal charge-transfer. Copyright

Hydrazides and Thiohydrazides as Sources of Condensed Oxadiazines and Thiadiazines, Including Novel Azo Derivatives Based on Dithizone

Condensation reactions of N’-phenylbenzohydrazide, N’-phenylbenzothiohydrazide, and dithizone with a variety of activated aromatic and heteroaromatic 1,2-dihalogeno and 1-halogeno-2-nitro compounds are described in which the hydrazide or thiohydrazide functions as a bidentate nucleophile.These reactions lead to derivatives of the 4H-1,3,4-benzoxadiazines and 4H-1,3,4-benzothiadiazines and analogous pyrimido-, pyrazino-, and quinoxalinooxadiazines and -thiadiazines which are representative of new ring systems.The corresponding reaction of N’-phenylbenzothiohydrazide with chloranil proceeds with expulsion of sulfur.The mechanism of this reaction is discussed.

Synthesis and Physical Properties of Pyrido[1?,2? : 1,2]imidazo[4,5-b]quinoxalines

A series of 2-, 3-, or 4-substituted pyrido[ 1?,2? : 1,2]imidazo[4,5-b]quinoxalines (PIQs) were synthesized in moderate-to-good yields by the reactions of 2-amino-3-ehloroquinoxulines (ACQs) with substituted pyridines, and the structures were established. The reactions of ACQs with 3-phenoxycarbonyl and 3-benzoylpyridines gave the corresponding 2-substituted PIQs, while those with 3-methyl, 3-ethyl, 3-benzyl, 3-phenyl, 3-ethoxycarbonyl, and 3-acetylpyridines gave the corresponding 4-substituted PIQs. PIQ derivatives having substituents at the 2,4,8, and/or 9-positions were also studied. The spectroscopic and electrochemical properties of a series of PIQs derivatives were studied. PIQ showed a strong green fluorescence at 481.5 and 505 nm (Phi = 0.40) in ethanol. The introduction of substituents at the 3 position of PIQ altered the color of the fluorescence from blue to green without deteriorating the high quantum yield of PIQ. All of the derivatives showed strong (blue to orange) fluorescence in both solution and the solid state.

Regioselective halogenation of pyridinium N-(benzoazynyl) aminides as a way to produce N-benzyl-alpha-aminobenzoazines

The halogenation of pyridinium N-(benzoazynyl) aminides with N-halosuccinimides provides a mild and regioselective method to functionalize the negatively charged diazine moiety in most cases. In some examples, however, formation of other products is explained. Finally, alkylation of the exocyclic nitrogen and reduction of the N?N bond provides a simple and straightforward strategy to obtain functionalized N-benzyl-benzoazynyl-alpha-amines.
