the studies performed about electrochemical oxidation 2-amino-4-methylphenol indicate that ortho-quinone yielded through oxidation of this chemical compound was unstable and it could be used as michael acceptor under solvent influences, carrier electrolyte, additives and could be transformed into the various compounds in the form of 1-4 addition michael reaction. based on this, in the paper fir...

Crystals of the title salt, C(17)H(28)NO(3) (+)·C(4)H(3)O(4) (-), were obtained by reacting parthenolide with dimethyl-amine followed by conversion of the amine adduct into a water-soluble fumarate salt. Subsequent crystallization of the fumarate salt from water afforded colorless ortho-rhom-bic crystals. The amine addition is highly stereospecific yielding exclusively a single diastereomer wit...

Two potentially heptadentate (N4O3) tripodal Schiff-base ligands: tris(3(salicylideneimino)propyl)amine (H3L1) and tris(3-(4'-hydroxysalicylideneimino)propyl)amine (H3L2) have been prepared and characterized by various spectroscopic methods (IR, FAB-MS, NMR). They are derived from the condensation reactions of tris(3-aminopropyl)amine (tpt), with 3 equivalents of either salicylaldehyde or the r...

Structure-activity relationship studies of diaryl amine-type KSP inhibitors were carried out. Diaryl amine derivatives with a pyridine ring or urea group were less active when compared with the parent carboline and carbazole derivatives. Optimization studies of a lactam-fused diphenylamine-type KSP inhibitor revealed that the aniline NH group and 3-CF3 phenyl group were indispensable for potent...

The spontaneous oxidation of an amine group to an imine has been observed experimentally in an octa-aza macrocyclic dinucleating ligand LH(4) coordinated to Cu(II). The reaction is bimolecular and spontaneous in which amine groups of one macrocycle are oxidised and the Cu(II) centres of a second macrocyclic complex are reduced. No additional oxidating or external base agents are required. DFT c...

The mononuclear neutral title complex, [Ni(NCS)(2)(C(10)H(9)N(3))(2)], shows a cis-octa-hedral geometry around the Ni(II) ion, formed by two chelating di-2-pyridyl-amine (Hdpa) ligands and two thio-cyanate anions. Both amine H atoms are involved in N-H⋯S hydrogen bonding, resulting in the formation of layers of inter-linked mol-ecules parallel to the ab plane, which are further held together by...

known to have a coordination number of seven. Nearly all of them have the basic formulation [Ln(bidentate)3(unidentate)]. On the contrary, structurally characterized examples of a heptadentate ligand coordinating one metal ion are rare. Tris(2-aminoethyl)amine (tren) condenses with salicylaldehyde or its substituted analogs in a 1:3 molar ratio to form Schiff-bases which are potentially tribasi...

It has been suggested that fluorescence from amine-containing dendrimer compounds could be the result of a charge transfer between amine groups and molecular oxygen [Chu, C.-C.; Imae, T. Macromol. Rapid Commun. 2009, 30, 89.]. In this paper we employ equation-of-motion coupled cluster computational methods to study the electronic structure of an ammonia-oxygen model complex to examine this poss...
