Stable gold(III) complexes with thiosemicarbazone derivatives.
Novel thiosemicarbazonato complexes of gold(III) have been prepared from reactions of [Au(damp-C1,N)Cl2(damp- = 2-(N,N-dimethylaminomethyl)phenyl) or [NBu4][AuCl4] with 2-pyridineformamide thiosemicarbazones (HL). The thiosemicarbazones deprotonate and coordinate as mononegative, tridentate NNS ligands to gold to give [Au(Hdamp-C1)(L)]Cl2 or [AuCl(L)]Cl complexes. The organometallic damp- ligan...
متن کاملGold(III)–pyrrolidinedithiocarbamato Derivatives as Antineoplastic Agents**
Transition metals offer many possibilities in developing potent chemotherapeutic agents. They are endowed with a variety of oxidation states, allowing for the selection of their coordination numbers and geometries via the choice of proper ligands, leading to the tuning of their final biological properties. We report here on the synthesis, physico-chemical characterization, and solution behavior...

use by the OPCW inspectorate. Use of GC with one or more spectrometric technique such as mass spectrometry is required to conRrm the presence of chemical warfare agents. For this reason many analyses are carried out by GC-MS under electron impact or chemical ionization conditions. For analyses involving low levels of chemical warfare agents in the presence of high levels of interfering chemical...
متن کاملAnsa·metallocene Derivatives Iii *. Influence of an Interannular Ethylene Bridge on the Reactivity of Titanocene Derivatives
Titanocene derivatives with an interannular ethylene bridge, while resem· bling their unbridged counterparts in many transformations involving Ti or TillI oxidation stages, do not follow reaction paths previously observed for unbridged titanocene in a number of reactions, such as formation of a TiII dinitrogen complex, isotope exchange of the cyclopentadienyl riIig ligands with D 2, or formatio...
متن کاملSynthesis and antimicrobial activity of new adamantane derivatives III.
Some novel ester imides synthesised from trimellitic acid anhydride and 1-adamantanol or 2-adamantanol, were tested as antimicrobial compounds. Unfortunately, these agents showed a modest antibacterial activity (MIC > 6 microg/ml). However, a comparison of these N-substituted adamantylester imides with the series published previously, indicated that the incorporation of L-alanine and L-phenylal...
