Bioorganometallic Chemistry

Organometallic compounds with biologically active molecules: in vitro antibacterial and antifungal activity of some 1,1-(dicarbohydrazono) ferrocenes and their cobalt(II), copper(II), nickel(II) and zinc(II) complexes (p 1207-1214)

	1,1-(dicarbohydrazono) ferrocenes prepared by condensing 1,1-diacetylferrocene with 2-furoic hydrazide, 2-thiophenecarboxylic hydrazide and 2-salicylic hydrazide respectively. These were characterized by spectral and analytical data and then were used for complexation with Co (II), Cu (II), Ni (II) and Zn (II) metals. The synthesized compounds were screened for their in-vitro antibacterial activity against Escherichia coli,lebsiella pneumonae, Proteus mirabilis, Pseudomonas aeruginosa, Salmonella typhi, Shigella dysentriae, Bacillus cereus, Corynebacterium diphtheriae, Staphylococcus aureous and Streptococcus pyogenes strains and for in-vitro antifungal activity against Trichophyton longifusus, Candida albicans, Aspergillus flavus, Microsporum canis, Fusarium solani and Candida glaberata.

	This article describes a simple and efficient synthesis procedure for isotopically enriched monoethylmercury chloride (C₂H₅ ²⁰¹HgCl) from commercially available ²⁰¹HgO (98.11% isotopic purity) and tetraethylin.

Materials, Nanoscience and Catalysis

A comparative study on aldol-type condensation reactions of cyclic, acyclic and substituted cyclicetones by the W(CO)₆/CCl₄/UV system (p 1220-1224)

DOI: 10.1002/aoc.983


	Aldol-type condensation reactions of a number of cyclic-, acyclic- and substituted cyclic-ketones were investigated by the W(CO)₆/CCl₄/UV system.

Synthesis and characterization of phosphorescent cyclometalated iridium complexes containing 2,5-diphenylpyridine based ligands (p 1225-1231)

DOI: 10.1002/aoc.985


	The four phosphorescent cyclometalated iridium complexes with 2,5-diphenylpyridine based ligands have been synthesized and characterized to investigate the effect of the simple ligand modification on photophysics, thermostability and electrochemistry.

New preparation of gold-silver complexes and optical fibre environmental sensors based on vapochromic [Au₂Ag₂(C₆F₅)₄(phen)₂]_n (p 1232-1238)

DOI: 10.1002/aoc.994


	The organometallic vapochromic mate- rial [Au₂Ag₂(C₆F₅)₄(phen)₂]_n is able to detect volatile organic compounds such as acetone, even in water solution, by implementation in an optical fibre sensor via a sol-gel doped with the vapochromic complex deposited onto a monomode fibre connected to a coupler.

	A new method for the preparation of Pd(0)/PANI nanocomposites is presented. This material shows good activity as catalyst in both Suzuki-Miyaura and Heck couplings.

Main Group Metal Compounds

1,1-Organoboration of silylethynyltin compounds studied by multinuclear magnetic resonance spectroscopy: isomerization at the CC bonds and electron-deficient SiHB bridges (p 1249-1256)
Bernd Wrackmeyer, Oleg L. Tok, Azimhan, Amin Badshah
Published Online: Oct 13 2005 9:47AM
DOI: 10.1002/aoc.924


	1,1-Organoboration using triethyl-, triallyl- and triphenylborane (BEt₃, BAll₃, BPh₃) of dimethysilylethynyl(trimethyl)stannane, Me₃SnCCSi(H)Me₂, affords alkenes bearing three different organometallic groups at the CC bond. Isomerisation (cis/trans) is caused by consecutive 1,1-deorganoboration and 1,1-organoboration. Electron-deficient SiHB bridges are identified by characteristic NMR parameters. All products were characterised by multinuclear NMR spectroscopy (¹H, ¹¹B, ¹³C, ²⁹Si and ¹¹⁹Sn NMR).

A convenient synthesis of methylindium(III) dithiolate complexes - precursors for indium sulfides (p 1257-1262)

DOI: 10.1002/aoc.981


	Reaction of trimethylindium with tris(dithiolato) indium(III) in appropriate stoichiometry readily yields methylindium(III) dithiolates. These complexes have been characterized using IR, NMR and mass spectral techniques. Their suitability as precursors for deposition of indium sulfides has also been evaluated.

	The antimony analogue of choline and a supramolecular sodium complex of stiba betaine have been synthesized and characterized by single crystal X ray diffraction and other methods.

Luminescence characteristics and X-ray crystal structure of [Cd(bipy)₃][PF₆]₂ (bipy = 2,2-bipyridine) (p 1268-1270)

DOI: 10.1002/aoc.996


	The [Cd(bipy)₃][PF₆]₂ complex exhibits a moderately large quantum yield of 1.07 × 10^-2, in acetonitrile solution at 25 °C, a result that is ascribed to the complexation of cadmium(II) by three 2,2-bipyridine ligands in a distorted octahedral geometry.
