Mechanisms of Acid Decomposition of Dithiocarbamates. 5. Piperidyl Dithiocarbamate and Analogues
The Journal of Organic Chemistry, 2008In 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.

Mechanisms of Acid Decomposition of Dithiocarbamates. 1. Alkyl Dithiocarbamates
The Journal of Organic Chemistry, 1998The 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.

Stereoelectronic Mapping of Dithiocarbamates and Xanthates
Inorganic Chemistry, 2022A library of 12 palladium(II) complexes of the type [PdBr(iPr2-bimy)(L∧X)] comprising 10 dithiocarbamato (R2NCS2-) and two xanthato (ROCS2-) ligands have been prepared and fully characterized. With these complexes in hand, the electronic and steric properties of the bidentate, monoanionic ligands were evaluated using the HEP2 and %Vbur methodologies ...

Pesticide Residues: Dithiocarbamates
2014Dithiocarbamates 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.

Complexation reactions of dithiocarbamates
Talanta, 1967The 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.

Cytotoxicity studies on dithiocarbamate fungicides
Toxicology and Applied Pharmacology, 1977Abstract 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 ...

Organic Letters, 2017
A facile and efficient procedure for the synthesis of substituted thiazole-2(3H)-thiones and thiazolidine-2-thiones by the reaction of primary amines, carbon disulfide, and nitroepoxides is described. By using secondary amines in this protocol, the corresponding dithiocarbamate-substituted phenyl-2-propanones were prepared in excellent yields.

Spectrophotometric determination of some dithiocarbamates
Talanta, 1990A procedure has been developed for the determination of six dithiocarbamates [sodium dimethyldithiocarbamate (dibam), sodium diethyldithiocarbamate (NaDDC), tetramethylthiuram disulphide (thiram), zinc dimethyldithiocarbamate (ziram), sodium N-methylpiperazinecarbodithioate and potassium morpholine-4-carbodithioate] in microgram quantities by ...

Dithiocarbamate-Capped Silver Nanoparticles
The Journal of Physical Chemistry B, 2006Nanometer-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.

Antiradiation Compounds. II. Dithiocarbamates
Journal of Medicinal and Pharmaceutical Chemistry, 1962Substituted 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 ...
