Molecular structure of (diethyldithiocarbomoyl)diphenylthiophosphinate

X-Ray study of (diethyldithiocarbomoyl)diphenylthiophosphinate was carried out. AZ-conformation of the diethyldithiocarbomoyl ligand, which results in a short nonvalent intramolecular P...S contact (3.315 Å), is realized in the molecule. Steric hindrances in the molecule increase the P-S-C bond angle to 106.39°.Translated fromIzvestiya Akademii Nauk.

Synthesis, properties, and structure of dimethylgold(III) complexes [(CH3)2AuI]2 and (CH3)2AuS2CN(C2H5)2

Volatile diethyldithiocarbamate of dimethylgold(III) was prepared by the interaction of dimethylgold(III) iodide with sodium diethyldithiocarbamate. The complex is examined by the elemental analysis, DTA, IR and electronic spectroscopy. The starting dimeric complex [(CH₃)₂AuI]₂ and a novel monomeric volatile gold(III) complex (CH₃)₂AuS₂CN(C₂H₅)₂ with the AuC₂S₂ coordination core were investigated by single crystal X-ray diffraction for the first time.

Über Chalkogenolate. 206 [1]. N-Thioacetyldithiocarbamate und Ester der N-Thioacetyldithiocarbamidsäure

On Chalcogenolates. 206. N-Thioacetyl Dithiocarbamates and Esters of N-Thioacetyl Dithiocarbamic Acid Thioacetamide reacts with carbon disulfide in the presence of KH to form via the tetrabutyl ammonium salt dark yellow N-thioacetyl dithiocarbamates M[S₂C? NH? CS? CH₃], where M = K, Rb, Cs. The salts as well as the methyl and ethyl ester have been characterized by means of electron absorption, infrared, nuclear magnetic resonance (¹H and ¹³C), and mass spectra. Attempts to synthesize N-thioacetyl dithiocarbamic acid were not successful.     

Facile,Three-Component Synthesis of Dithiocarbamate Derivatives With Potent Antimicrobial Activity

A one-pot three component synthesis of alkyl/aryl-dithiocarbamic acid-3-oxo-3-(phenoxathiin-2-yl)-1-phenyl/(4-chlorophenyl)propyl esters (3a–n) was achieved from the reaction of 3-phenyl/(4-chlorophenyl)-1-(phenoxathiin-2-yl)propenones (1a,b), amine, and carbon disulfide. The antimicrobial activities of some compounds were also screened against some selected bacteria and fungi.

Mechanism of mass spectral fragmentation of dinuclear copper(ii) complexes with heterocyclic dithiocarbamates and octaazamacrocyclic ligand

The mass spectral fragmentation of five dinuclear Cu(II) complexes of the general formula [Cu₂(Rdtc)tpmc] (ClO₄)₃, where tpmc and Rdtc refer to N, N, N, N-tetrakis(2-pyridylmethyl)-1,4,8,11-tetraazacyclotetradecane and piperidine- (Pipdtc), 4-morpholine- (Morphdtc), 4-thiomorpholine- (Timdtc), piperazine- (Pzdtc), or N-methylpiperazine- (N-Mepzdtc) dithiocarbamates, respectively, has been investigated. The results were shown to be of mechanistic significance, clarifying the major products of their fragmentation. A possible mechanism entails a multi-step decomposition process that can be separated into individual steps depending on their molecular structures. Every step is determined to some extent by the nature of the intermediates.__________Published in Zhurnal Prikladnoi Spektroskopii, Vol. 72, No. 1, pp. 38–42, January–February, 2005.     

Regioselective Michael-induced cyclisation of γ- and δ-hydroxy vinyl sulfides and vinyl dithiocarbamates

We herein describe the unprecedented use of heteroaryl vinyl sulfides and vinyl dithiocarbamates as hetero-Michael addition acceptors. Combined chelating and electron-withdrawing effects are postulated to stabilise the transient anionic species and allow smooth Michael-induced ring closure to produce diversely functionalised C-glycosides.     

Zur Reversed-phase-Chromatographie von Metallchelaten

Zusammenfassung In der Reversed-phase-Chromatographie wurde für Metallchelate am Beispiel von Kupferdithiocarbamaten der Rf-Wert näherungsweise als lineare Funktion folgender Parameter ermittelt: Kettenlänge des Carbamats, Wassergehalt der mobilen Phase und Anzahl der C-Atome in der Kette der stationären, chemisch-gebundenen Phase. Die genannten Funktionen werde vom Kupfer-bis-diethyledithio-carbamat am besten erfüllt. Die Untersuchungen wurden dünnschichtchromatographisch an Fertigplatten durchgeführt. Weiterhin wurden die Verteilungskoeffizienten zwischen unpolaren, flüssigen Modellphasen und einem Gemisch aus Acetonitril und Wasser (91) bestimmt. Als geeignete Modellphase für die chemisch-gebundene Octylphase (RP-8) erwiesen sich Octan und Isooctan. Die Abhängigkeit des Verteilungskoeffizienten von den entsprechenden Parametern ist umgekehrt der Rf-Wert-Funktionen.

Reversed-phase chromatography of metal chelatesI. Relations between liquid-liquid partition, chromatographically behaviour and structure of the chelating reagents by the expression of copper dithiocarbamates

Summary In the reversed-phase-chromatography on the exemplary use of copper dithiocarbamates it was demonstrated that the Rf value is linear dependent of the chain length of the chelat, on the water content of the mobile phase and the number of the C-atoms in the chain of the stationary, chemically-bonded phase. The functions are the best fullfilled by copper bis-diethyldithiocarbamate. The examinations were carried out by thin-layer chromatography on pre-coated sheets. Furthermore we determineted the partition coefficients between an unpolar, liquid model phase and a mixture of acetonitrile and water (91). The best model phases for a chemicallybonded octylphase were octane or isooctane. The dependence on the partition coeffizient of the correspondending parameters of the Rf value is inverse.

     

An Approach to Paracyclophane-Based Tetrathiafulvalenes: Synthesis and Characterization of a Pseudo-Geminal [2.2]Paracyclophane 1,3-Dithia-2-Thione

The synthesis of paracyclophane-based tetrathiafulvalene precursors is described in the context of the importance of these compounds in the field of material chemistry. Pseudo-geminal bis(1,3-dithia-2-thione) was synthesized via the corresponding 1,3-dithiol-2-ylium salt. The latter was obtained by a synthetic procedure that involves 4,15-bis(acetyl)[2.2]paracyclophane, a new compound of interest for many researchers.
