Nano dithiocarbamate (DTC) complex have been prepared by reaction between dithiocarbamate and metal salt under ultrasound irradiation. Reaction conditions such as the ligand DTC and phennantroline concentration, aging time and the ultrasonic device power show important roles in the size, morphology and growth process of the final products. The dithiocarbamate complex nanoparticles have been pre...

Unnatural α-amino acids containing dithiocarbamate side chains were synthesized by a one-pot reaction of in situ generated dithiocarbamate anions with sulfamidates. A wide range of these anions participated in the highly regio- and stereo-selective ring opening of sulfamidates to produce the corresponding dithiocarbamate pendant α-amino acids in high yields.

This paper describes the use of a phenyl bis(dithiocarbamate) (PBTC) linker to enhance the quantum yield of photoinduced electron transfer (eT) from a zinc porphyrin (ZnP) molecule (donor) to a CdSe quantum dot (QD) (acceptor), where quantum yield is defined as the fraction of photoexcited ZnP molecules in the sample that donate an electron to the QD. The PBTC ligand links the ZnP to the QD by ...

Pesticide misuse by farmers poses health risks to consumers. This study assessed the level of dithiocarbamate residues in tomatoes acquired from 20 farmers and 25 market vendors in Wakiso District, how simple washing affects these residues, and the potential chronic health risk for Ugandans eating such tomatoes. Results revealed that mancozeb was the only reported dithiocarbamate, and 47.4% and...

Abstract Lubricants have played important roles in friction and wear reduction increasing efficiency of mechanical systems. To optimize tribological performance, chemical reactions between a lubricant substrate must be designed strategically. Tribochemical are enabled or accelerated by stimuli. Tribochemically activated additives play these reactions. In this review, current understanding mecha...

In this research, the synthesis and biological activity evaluation of N, N`-(ethane-1,2-diyl)bis(1-phenyl methanimine) as Schiff base with Zinc (II) dithiocarbamate complex are successfully reported. The suggested geometry around zinc ion centre was determined using selected unique physicochemical spectroscopic techniques. These include melting point, conductance, FTIR, UV-Vis, mass spectroscop...

In this study, twenty two new N,N-disubstituted dithiocarbamate derivatives were synthesized. The structures of the compounds were confirmed by IR, 1H-NMR, mass spectroscopy and elemental analysis. Anticholinergic activities of the compounds were evaluated by the tests performed on isolated rat ileum and were compared with atropine sulfate. 1-(Diphenylamino)-1-oxopropan-2-yl 4-methylpiperazine ...
