The synthesis and characterization of palladium(II) complexes featuring β‐ketoiminato ligands type [Pd(ArNacac)2] (4) with Ar = 2‐chlorolphenyl (a); 3‐chlorophenyl (b); 4‐chlorophenyl (c); 2,3‐dichlorophenyl (d); 2,4‐dichlorophenyl (e); 2,6‐dichlorophenyl (f); 3,5‐dichlorophenyl (g); 2,4,5‐trichlorophenyl (h); 2,4,6‐trichlorophenyl (i) is reported. molecular structure 4a‐f, h 4i in the solid state was confirmed by single‐crystal X‐ray diffraction studies. All eight crystal structures are...
Crystal structures of six iodopyridinium tetrahalocuprate(II) salts are reported, (nIP)2CuX4, where X = Cl or Br, nIP is the n-iodopyridinium cation, and n 2, 3, 4. The supramolecular structure these developed based on N–H···X hydrogen bonding C–I···X halogen interactions. Comparing with previously published general formulas (nCP)2CuX4 (nBP)2CuX4, nCP+ nBP+ n-chloropyridinium n-bromopyridinium cations, respectively, allows us to investigate competition between Henceforth, formula (nYP)2CuX4...
A potassium 4-(ethoxycarbonyl)phenyldithiocarbamate, (4-etphdtc), and 6-ethoxybenzothiazol)-dithiocarbamate, (6-etbedtc), ligands have been isolated four metal dithiocarbamate complexes of the type [M(4-etphdtc)2] [M(6-etbedtc)2] (M = Zn, Cd;) were synthesized characterized by elemental analysis spectroscopic techniques (FT-IR,1H and13C{1H}-NMR, HRMS, UV–vis). Thermogravimetric studies all performed final product thermal decomposition was sulfides. The theoretical study with density...
The ruthenium aqua complexes [Ru(H(2)O)(2)(bipy)(2)](OTf)(2), [cis-Ru(6,6'-Cl(2)-bipy)(2)(OH(2))(2)](OTf)(2), [Ru(H(2)O)(2)(phen)(2)](OTf)(2), [Ru(H(2)O)(3)(2,2':6',2''-terpy)](OTf)(2) and [Ru(H(2)O)(3)(Phterpy)](OTf)(2) (bipy = 2,2'-bipyridine; OTf(-) triflate; phen phenanthroline; terpy terpyridine; Phterpy 4'-phenyl-2,2':6',2''-terpyridine) are water- acid-stable catalysts for the hydrogenation of aldehydes ketones in sulfolane solution. In presence HOS(O)(2)CF(3) (triflic acid) as a...
A green method was developed for the synthesis of CuFe2O4 magnetic nanoparticles using a Neem leave extract. The prepared with an average size 19.7 nm were used as effective catalyst oxidation various aryl alkanes in moderate to excellent yields under solvent-free conditions. characterized by powder- XRD, SEM and TEM study. key advantages this protocol are simple preparation, recyclable heterogeneous catalytic system, benign reaction condition good high selectivity toward acid (42–87%).
The dibridgehead diphosphine ((CH2)14)3 P (1) can rapidly turn inside-out (homeomorphic isomerization) to give a mixture of in,in and out,out isomers. exo directed lone pairs in the latter are able scavenge Lewis acidic MCl2; cagelike adducts isomer, trans- Cl2(P((CH2)14)3 P) (M = 2/Pt, 3/Pd, 4/Ni), then form. NiCl2 unit 4 may be replaced by PtCl2 or PdCl2, but 2 3 do not similar substitutions. U-tubes charged with CH2Cl2 solutions 1 (lower phase), an aqueous solution K2MCl4 (charging arm; M...
When an in , out isomer of a macrobicyclic dibridgehead diphosphine is combined with two equiv. gold( i ) Lewis acid sufficient bulk, the resulting adduct obtained as topologically novel “crossed chains”.
Treatment of 3,4-(ClC(O))2-cC4H2S (1) with [FcCH2OLi] (2-Li) (Fc = Fe(η5-C5H5)(η5-C5H4)) in a 1:2 ratio gave 3,4-(FcCH2OC(O))2-cC4H2S (3). Compound 3 decomposes solution during crystallization to produce FcCH2OH (2) along 3,4-thiophenedicarboxylic anhydride (4). The cyclic voltammogram exhibits reversible ferrocene-related redox couple (E1/2 108 mV, vs. Cp2Fe/Cp2Fe+) using [NnBu4] [B(C6F5)4] as the supporting electrolyte. DFT calculations reveal that energy values LUMO orbitals...
Silylated organoselenium reagents react under mild conditions with acid chlorides to provide a high yield route aromatic selenoesters.

Abstract Lithium (trimethylsilyl)chalcogenolates have been generated and used to prepare a series of alk‐2‐ynyl trimethylsilyl chalcogenoethers from the corresponding propargyl bromides in good yield. The thermal decomposition telluroethers has also studied. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
Halogen bond interactions are investigated in four halopyridine iodine monochloride complexes nXPy(N)–ICl the solid state, solution and silico, where nXPy = n-halopyridine, X I or Br n 2 3. Two types of halogen bonding were observed: stronger three-center Py(N)–ICl bonds weaker two-center Py(C)–X···Cl bonds. Theoretical calculations (thermodynamic data optimized distances) NMR studies indicated that 3XPy(N)–ICl than 2XPy(N)–ICl complexes. In relying on distances, nBrPy(N)–ICl show same...
