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 ...

Eighteen new 5-benzylidene-3-(4-arylpiperazin-1-ylmethyl)-2-thioxo-imidazolidin-4-ones were designed as hybrid structures from previously reported anticonvulsant compounds, synthesized and tested for anticonvulsant activity. Initial anticonvulsant screening was performed using the strychnine (2 mg/kg IP) potent generalized-induced seizure and pentylenetetrazole (PTZ) (60 mg/kg IP) acute clonic-...

On the basis of our earlier studies in a group of 7,8-disubstituted derivatives of 1,3-dimetyl-3,7-dihydropurine-2,6-dione, a series of new 8-alkylamino-1,3-dimethyl-7-(2-hydroxy-3-aminopropyl)-3,7-dihydropurine-2,6-diones (8-15) were synthesized and tested for their electrocardiographic, antiarrhythmic and hypotensive activity and for α(1)- and α(2)-adrenoreceptor affinities. Among the new der...

After modifying 53 items in a previous Dutch translation of the Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ; Livesley & Jackson, 2002), the present DAPP-BQ scales (with or without Self-Harm included) were subjected to a principal components analysis with oblimin or varimax rotation in a general population sample of 478 subjects, retaining four factors. All four ...

As discharge restrictions become stricter and sludge dlisposal costs rise, traditional technologies for the removal of metals from plating shop wastewater such as lime and ferric chloride become increasingly less attractive. One technology that is of use of dithiocarbamates to complex a highly insoluble, dense sludge, effluent water and greatly reduced sludge volumes. Despite the benefits avail...

A one-pot preparation of pyridyl isothiocyanates (ITCs) from their corresponding amines has been developed. This method involves aqueous iron(III) chloride-mediated desulfurization of a dithiocarbamate salt that is generated in situ by treatment of an amine with carbon disulfide in the present of DABCO or sodium hydride. The choice of base is of decisive importance for the formation of the dith...

A dithiocarbamate-based methodology is employed to prepare linked heteromultimetallic complexes and then further exploited in the surface functionalisation of gold nanoparticles.
