Synthesis, chemistry and structures of complexes of the dioxovanadium(V) halides VO2F and VO2Cl.

Thermodynamic study of dioxovanadium (V) Complexes with p-sulphonato-calix [6] arene in aqueous solution

Solvent Effects on Complexation of Dioxovanadium (V) with Glycine in Methanol-Water Mixtures

The formation constants of the species formed in the systems fr + glycine + dioxovanadium(V) + and H+ + glycine have been determined in aqueous solutions of methanol at 25 °C and constant ionicstrength, using spectrophotometric and potentiometric techniques. It was shown thatdioxovanadium(V) forms two mononuclear 1 : land 1:2 complexes with glycine. The formationconstants in various media were ...

Palladium(II) Phosphine-Ylide Complexes as Highly Efficient Homogeneous Pre-catalysts for the Ullmann Homocoupling Reaction of Aryl Halides

A highly efficient Ullmann homocoupling reaction of aryl halides using palladium (II) phosphine-ylide complexes as homogenous pre-catalysts under aerobic conditions has been developed without the need for any chemical co‐reducing agents. The procedure is relatively mild and appears to have broad applicability, being useful for the homocoupling of both electron-deficient and electron-rich aryl h...

Synthesis, Characterization and Antibacterial Activity Studies of Some N-Acyl-N'-aryl Thiourea Derivatives

Some N¬-acyl-N'-aryl thiourea derivatives 4(a-f) have been prepared by the reaction of acyl halides ammonium thiocyanate and aryl amines. The structures of synthesized compounds have been characterized by IR, 1HNMR spectral studies. The synthesized compounds 5(a-f) have been screened for antibacterial activity. The effect of the structure of the investigated compounds on the antibacterial activ...

Synthesis, Spectral Characterization and DFT Calculations of New Co(II) Complexes Derived from Benzimidazoles

The synthesis, characterization and quantum-chemical investigations of two new Co(II) complexesderived from fluorescent benzimidazoles have been reported. Two new fluorescentheterocyclic ligands were synthesized from the reduction of imidazo[4',5':3,4]benzo[1,2-c]isoxazole derivatives, and characterized by elemental analyses, IR, mass, and NMR spectra. Coordination of the bidentate ligands ...
