Phosphorus-based Mannich-type reactions (phospha-Mannich reactions) of primary or secondary phosphines with carbonyl compounds and amines (R2NH, RNH2, NH3) provide a powerful synthetic tool in the worldwide search for future ligands. The variety available allows designing fine-tuning water-soluble, chiral, macrocyclic, pincer, tripodal, photoactive, etc., phosphine ligands P–C–N linkage(s) (P,N...

Tuberculosis (TB) is the fastest spreading infectious disease and one of top ten diseases that kill millions people annually. The rapid spread a multidrug-resistant strain Mycobacterium tuberculosis leads to multidrug-resistance (MDR-TB), which very difficult treat. Filament temperature-sensitive protein ring-Z (Ftsz) could be best target inhibit bacterial cytokinesis. This research conducted p...

Biogenic amine receptors play critical roles in regulating behavior and physiology in both vertebrates and invertebrates, particularly within the central nervous system. Members of the G-protein coupled receptor (GPCR) family, these receptors interact with endogenous bioamine ligands such as dopamine, serotonin, and epinephrine, and are targeted by a wide array of pharmaceuticals. Despite the c...

A series of palladium(II) complexes incorporating di-NHC-amine ligands has been prepared and their structural, dynamic and catalytic behaviour investigated. The complexes [trans-(kappa(2)-(tBu)CN(Bn)C(tBu))PdCl(2)] (12) and [trans-(kappa(2)-(Mes)CN(H)C(Mes))PdCl(2)] (13) do not exhibit interaction between the amine nitrogen and palladium atom respectively. NMR spectroscopy between -40 and 25 de...

The title compound, [Fe(C 2 N 3 ) (C 8 H 7 5 ]·2H O, has been synthesized solvothermally and characterized by single-crystal X-ray diffraction. octahedral iron coordination polyhedron contains two di(pyrimidin-2-yl)amine ligands coordinated in a bidentate fashion, monodentate dicyanimido ligands, each via terminal atom, with the latter cis orientation. ligand configuration about atom is chiral,...

The title compound, {[Ag(L)]PF(6))(n) {L is tris-[2-(4-phenyl-1,2,3-triazol-1-yl)eth-yl]amine, C(30)H(30)N(10)}, consists of alternating two-dimensional cationic layers of [Ag(L)](+) and anionic PF(6) (-) layers. Each Ag(I) atom is three coordinated in a T-shaped geometry by three N atoms from three ligands. Each ligand links three Ag(I) atoms, generating a two-dimensional network structure wit...

In the title complex, [Pd(CH(3)COO)(2)(C(10)H(9)N(3))], the Pd(II) ion is four-coordinated in a slightly distorted square-planar environment by two pyridine N atoms of the chelating di-2-pyridyl-amine (dpa) ligand and two O atoms from two anionic acetate ligands. The dpa ligand coordinates the Pd(II) atom in a boat conformation of the resulting chelate ring; the dihedral angle between the pyrid...

In this paper are reported the results of a comprehensive mechanistic study of nucleophilic attack by amines on coordinated isocyanides in square—planar Pd(II) complexes, leading to amino—carbene complexes. The reactivity pattern that has emerged displays several facets: (i) whatever the details, in this stepwise mechanism the most prominent step always involves direct attack of the amine nitro...

The dehydrogenation of pyrrolyl-functionalized secondary amines initiated by rare-earth metal amides was systematically studied. Reactions of the rare-earth metal amides [(Me(3)Si)(2)N](3)RE(μ-Cl)Li(THF)(3) with pyrrolyl-functionalized secondary amines 2-(t)BuNHCH(2)-5-R-C(4)H(2)NH (R = H (1), R = (t)Bu (2)) led to dehydrogenation of the secondary amines with isolation of imino-functionalized p...
