Bazgir, Ayoob
, p. 1 - 2 (2007/10/03)
A simple and efficient method for synthesis of diimines using silica gel supported sodium hydrogen sulfate as reusable solid support in solvent-free conditions under microwave irradiation is described.
A novel decyanogenative coupling of α-cyanoimines mediated by samarium. A facile route to α-diketimines

, p. 102 - 103 (2007/10/03)
Conversion of α-cyanoimines 1 into α-diketimines 2 has been achieved successfully by using samarium diiodide in dry tetrahydrofuran in high yields without formation of anilinoanil 3, 1,2-diamines 4 or anilides 5.
Formation of benzil diimines by microwave-assisted reaction of benzil with aromatic amines on alumina surface without solvent
Singh,Mahajan
, p. 410 - 411 (2007/10/03)
The microwave-assisted solvent-free reaction of benzil with aromatic amines (in 1 : 2 molar ratio) on an alumina surface for 4 min affords benzil diimines (1,2,3,4-tetraaryl-1,4-diaza-1,3-butadienes).
A novel reductive dimerization/oxidative dehydrogenation of aldimines mediated by lanthanoid metals
Jin,Makioka,Kitamura,Fujiwara
, p. 514 - 520 (2007/10/03)
A lanthanoid metal-mediated novel reductive dimerization/oxidative dehydrogenation of a variety of aldimines has been achieved. Aromatic aldimines (1) were dimerized in the presence of 0.5 mol of ytterbium metal (Yb) and 1-naphthaldehyde (1-NpCHO) to give
Synthesis and characterization of 9,10-bis(arylimino)-9,10-dihydrophenanthrenes, the structure of (Z,Z)-9,10-bis(phenylimino)-9,10-dihydrophenanthrene and PdCl2-[(E,E)-9,10-bis(phenylimino)-9,10-dihydrophenanthrene] in the solid state and in so

, p. 57 - 62 (2007/10/02)
Two extreme situations in 1,4-diaza-1,3-diene (DAD) chemistry are described.Reaction of phenyl-substituted DAD 1a-c with lithium in the molecular ratio of 1:2 affords in high yield the extremely air-sensitive complexes (2a-c).The structure of 2b has been determined by X-ray diffraction.Each of the Li+ ions is coordinated by the two terminal N atoms of the s-cis-configurated DAD dianion and by two molecules of THF.Protonation of ZrCl4*DAD (3a) by HCl in THF gives the ionic complexes (4), which contains a protonated + cation.The structure of the sterically crowded N=C-C=N skeleton of the + cation is not influenced by the positive charge and adopts the unusual Z-gauche-Z conformation. Key Words: Lithium compounds / Enediamide structure / 1,4-Diaza-1,3-diene, protonated / Hydrogen bond
NOVEL AND CONVENIENT SYNTHESES OF SUBSTITUTED 1,4-DIAZOCINES AND 1,4-DIAZONINES
Singh, Geeta,Mehrotra, Kailash Nath
, p. 1341 - 1344 (2007/10/02)
Treatment of dianils with sodium in dry ether followed by addition of 1,4-dichlorobutane and 1,5-dichloropentane gave 1,2,3,4-tetraaryl-1,4,5,6,7,8-hexahydro-1,4-diazocines and 1,2,3,4-tetraaryl-4,5,6,7,8,9-hexahydro-1H-1,4-diazonines respectively.
