Antiradiation Compounds. II. Dithiocarbamates

Journal of Medicinal and Pharmaceutical Chemistry, 1962
Substituted dithiocarbamic acid derivatives, some of which contain metal- chelating functions additional to the dithiocarbamyl group, were synthesized as potential protective agents against ionizing radiation. It appeared that the additional nitrogen-containing chelating function contributed nothing to the radioprotective ability of dithiocarbamates ...

Pesticide Residues: Dithiocarbamates

2014
Dithiocarbamates are synthetic organic compounds containing sulfur and often a sulfur-bound metal, some of which are used to protect fruits and vegetables from fungal infections. Exposure of the general population results from occasional residues in foodstuff.

Dithiocarbamate-Capped Silver Nanoparticles

The Journal of Physical Chemistry B, 2006
Nanometer-sized silver particles were synthesized by using didecylamine dithiocarbamates as the protecting ligands. With control of the initial ligand-metal feed ratios, the core diameter of the resulting particles was found to vary from about 5 to 2.5 nm, as determined by transmission electron microscopic measurements.

Mechanisms of Acid Decomposition of Dithiocarbamates. 1. Alkyl Dithiocarbamates

The Journal of Organic Chemistry, 1998
The acid decomposition of some substituted methyldithiocarbamates was studied in water at 25 °C in the range of Ho −5 and pH 5. The pH−rate profiles showed a bell-shaped curve from which were calculated the acid dissociation constants of the free and conjugate acid species and the specific acid catalysis rate constants kH.

Mechanisms of Acid Decomposition of Dithiocarbamates. 5. Piperidyl Dithiocarbamate and Analogues

The Journal of Organic Chemistry, 2008
In this work, the acid cleavage at 25 degrees C in 20% v/v aqueous ethanol of a series of analogues of piperidine dithiocarbamate X(C2H4)2NCS2(-) (X = CH2, CHCH3, NH, NCH3, S, O) was studied. The pH-rate profiles were obtained in the range of H(o)-5 and pH 5.

Cytotoxicity studies on dithiocarbamate fungicides

Toxicology and Applied Pharmacology, 1977
Abstract The cytotoxicity of selected metal-containing dithiocarbamate fungicides was determined using Chinese hamster ovary cells (CHO-K1) in culture. Bis(dimethylthiocarbamoyl)disulfide (thiram) and ferric dimethyldithiocarbamate (ferbam) were more toxic, having LC50 values of 5 × 10−7 and 7 × 10−7 m , respectively, whereas manganese ethylene ...

Mesomorphic dithiocarbamate complexes

Polyhedron, 1997
Abstract Complexes of 4-(4′-alkyloxyphenylethyl)piperi dine dithiocarbamates with nickel, palladium, copper and zinc have been formed. The nickel and copper complexes are mesomorphic showing smectic phases S, and crystal B mesophases.

Triphenyltelluroniumcarbamate und ‐dithiocarbamate

Zeitschrift für anorganische und allgemeine Chemie, 1988
AbstractDurch Umsetzung von Triphenyltelluroniumchlorid mit den entsprechenden Natrium‐ bzw. Ammoniumsalzen von Dithiocarbaminsäuren bzw. Carbaminsäure erhält man Verbindungen des Typs (C6H5)3TeS2CNR2 (R  CH3, i‐C3H7, C6H5), sowie (C6H5)3TeO2CN(CH3)2.Darüberhinaus kann auf diese Weise auch der bifunktionelle Ethylen‐bis(N,N′‐methyldithio‐carbaminsäure‐

Complexation reactions of dithiocarbamates

Talanta, 1967
The complexation reactions of various disubstituted dithiocarbamates are discussed. Special attention is paid to studies of composition and stability of various metal complexes. The conditions of complex formation in solution are treated in terms of side-reaction coefficients.
