Dithiocarbamate fungicides such as maneb and mancozeb are widely used nonsystemic protectant fungicides to control various plant fungal diseases. Dithiocarbamate fungicides should be frequently applied to achieve optimal efficacy of disease control and avoid either decline in effectiveness or wash-off from leaf surface. Dithiocarbamates are of low resistance risk but have the potential to cause...

In this study, a new modified optical chemical sensor based on swellable polymer microspheres is developed using a 5% copolymer of polyvinylpyridine-polyvinyl-benzyl chloride microspheres functionalized as the corresponding dithiocarbamate. This sensor demonstrated significant enhancements in sensitivity, dynamic range and response time. These improvements are related to the presence of pyridin...

Isothiocyanates (ITCs) are organosulfur compounds derived from cruciferous plants. An electrophilic ITC group (-N=C=S) reacts with some functional groups such as a hydroxyl ion, thiol and amine in proteins. It is known that ITCs decomposed easily by the addition of ion to aqueous solutions. In intracellular behavior, primary target group, which results formation their dithiocarbamate conjugates...

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. The core size dispersity was also found to decrease with increasing feed ra...

Some pesticide chemicals are based on inorganic elements such as sulfur, copper (i.e. copper sulfate ‘Bordeaux mixture’, copper hydroxide, and copper oxychloride), and arsenic salts (i.e. lead arsenate, calcium arsenate, sodium arsenite), or they contain an inorganic element in their chemical structure such as the organometallic pesticides based on manganese dithiocarbamate (maneb), manganese a...

Dithiocarbamates (DTC) are organosulfur compounds represented by a general structure (R1R2)N-(C=S)-SX, where R can be substituted by an alkyl, alkylene, aryl, or similar other group, and X usually by a metal ion (Edwards, 1991; Kamrin, 1997; US EPA, 2001). Discovered in the 1930s, the DTC were first introduced as fungicides for commercial applications during World War II (Ware & Whitacre, 2004)...

The reaction of 3-aminopropylamide of cholic acid with CS₂ produced a bile acid derivative of dithiocarbamic acid which further formed an ammonium salt with another molecule of 3-aminopropylamide of cholic acid. The cationic 3-ammonium propylamide of cholic acid did not react further with CS₂ and the formed salt was stable in the reaction mixture, even when excess CS₂ was used. When the reactio...

A general and facile one-pot protocol for the preparation of a broad range of alkyl and aryl isothiocyanates has been developed from their corresponding primary amines under aqueous conditions. This synthetic process involves an in situ generation of a dithiocarbamate salt from the amine substrate by reacting with CS(2) followed by elimination to form the isothiocyanate product with cyanuric ac...

Reductive desulfurisation of dithiocarbamates is conveniently achieved using H(3)PO(2)-Et(3)N-ACCN in refluxing dioxane. Fused and spirocyclic β-lactams, prepared through 4-exo trig carbamoyl radical cyclisation-dithiocarbamate group transfer reactions, are reduced without fragmentation of the strained 4-membered ring. Diethyl tetraacetyl-d-glucopyranosyl dithiocarbamate is selectively reduced ...

A series of triorganophosphinegold(1) dithiocarbamate (R(3)PAuS(2)CNR'(2)) and xanthate (R(3)PAuS(2)COR') complexes have been prepared and characterised spectroscopically. Based on crystallographic evidence, the molecules feature linear gold(1) geometries defined by sulphur and phosphorus donors. The complexes, along with a series of known anti-cancer agents, have been screened against a panel ...
