The 1,2,3,4-thiatriazole-5-thiolate anion (TTT(-)) was found to be a strongly binding ligand for CdSe nanocrystals, quantitatively exchanging various long-chain ligands to yield stable colloidal suspensions in common polar solvents. The TTT(-) ligand thermolyzes at <100 °C to produce thiocyanate in situ, resulting in reduced quantum confinement in nanocrystal films. CdSe(TTT) possesses far high...

We report the synthesis, crystal structure and exfoliation of a new member of an important family of layered compounds: lamellar pyrimidinethiolate coordination polymers. Conductivity measurements and DFT calculations of iron(II) pyrimidine-2-thiolate show that this material and a related compound are insulators.

Abstract A series of M(II) and M(IV) (M=Mo, W) alkyne adducts employing two 6‐methylpyridine‐2‐thiolate (6‐MePyS) ligands was synthesized investigated towards the nucleophilic attack PMe 3 on coordinated alkynes. For this approach, 2‐butyne (C 2 Me ), phenylacetylene (HC Ph), diphenylacetylene Ph ) were used. exploration an intramolecular attack, but‐3‐yn‐1‐ol (HCCCH CH OH) to metal centers. ob...

Surface-enhanced Raman scattering (SERS) is an ultrasensitive analytical technique, which capable of providing high specificity; thus, it can be used for toxicological drug assay (detection and quantification). However, SERS-based analysis directly in human biofluids requires mitigation fouling nonspecificity effects that commonly appeared from unwanted adsorption endogenous biomolecules presen...

Hexadecanethiol (n-C16), 2,2-dimethylhexadecane-1-thiol (DMC16), and the multidentate thiol-based ligands 2-tetradecylpropane-1,3-dithiol (C16C2), 2-methyl-2-tetradecylpropane-1,3-dithiol (C16C3), and 1,1,1-tris(mercaptomethyl)pentadecane (t-C16) were evaluated for their ability to stabilize large gold nanoparticles (>15 nm) in organic solution. Citrate-stabilized gold nanoparticles (20-50 nm) ...

The biologically relevant S-alkylation reactions of thiolate ligands bound to a transition metal ion were investigated with particular attention paid to the role of the metal identity: Zn(II) versus Ni(II). The reactivity of two mononuclear diamine dithiolate Zn and Ni complexes with CH(3)I was studied. With the [ZnL] complex (1) (LH(2) = 2,2'-(2,2'-bipyridine-6,6'-diyl)bis(1,1-diphenylethaneth...

Deprotection of an N(α)-Fmoc-protected glycocysteine derivative 7 with an excess of morpholine unexpectedly led to the fluorenylmethyl-protected thioether 8 in high yield. The suggested mechanism for this reaction comprises the addition of the cysteine thiolate on the exocyclic double bond of dibenzofulvene, which is formed during Fmoc deprotection. The influence of base concentration on this t...
