Usage

General Description

Benzenethiol, potassium salt is a chemical compound that is composed of a benzene ring attached to a sulfur atom with a potassium cation. It is commonly used in organic synthesis as a source of benzenethiol, a compound that is often used in the production of pharmaceuticals, polymers, and dyes. Additionally, it can be used as a reagent in chemical reactions to facilitate the introduction of a thiol group into organic molecules. Benzenethiol, potassium salt is also used as a catalyst in some organic reactions and as an intermediate in the production of other chemical compounds. It is typically handled and stored with care due to its reactivity and potential hazards.

Utility of a redox-active pyridine(diimine) chelate in facilitating two electron oxidative addition chemistry at uranium

Exposure of the uranium(iv) complex, CpPU(MesPDI Me) (1) (MesPDIMe = 2,6-((Mes)NCMe) 2-C5H3N; Mes = 2,4,6-trimethylphenyl; Cp P = 1-(7,7-dimethylbenzyl)cyclopentadienyl), which contains a [ MesPDIMe]3- chelate, to I2, Cl 2, PhSeCl, and PhEEPh (E = S, Se, Te) results in oxidative addition to form the uranium(iv) family, CpPU(XX′)( MesPDIMe) (X = X′ = I, Cl, EPh; X = SePh, X′ = Cl). Spectroscopic and structural studies support products with [ MesPDIMe]1-, indicating the reducing equivalents derive from this redox-active chelate. This journal is the Partner Organisations 2014.

Inherent Reactivity of Spiro-Activated Electrophilic Cyclopropanes

The kinetics of the ring-opening reactions of thiophenolates with geminal bis(acceptor)-substituted cyclopropanes in DMSO at 20 °C was monitored by photometric methods. The determined second-order rate constants of the SN2 reactions followed linear relationships with Mayr nucleophilicity parameters (N/sN) and Br?nsted basicities (pKaH) of the thiophenolates as well as with Hammett substituent parameters (σ) for groups attached to the thiophenolates. Phenyl-substituted cyclopropanes reacted by up to a factor of 15 faster than their unsubstituted analogues, in accord with the known activating effect of adjacent π-systems in SN2 reactions. Variation of the electronic properties of substituents at the phenyl groups of the cyclopropanes gave rise to parabolic Hammett relationships. Thus, the inherent SN2 reactivity of electrophilic cyclopropanes is activated by electron-rich π-systems because of the more advanced C1?C2 bond polarization in the transition state. On the other hand, electron-poor π-systems also lower the energetic barriers for the attack of anionic nucleophiles owing to attractive electrostatic interactions.

Nucleophilic Cleavage of the Ether Bond of Chlorex in the Chalcogenation with Diphenyl Dichalcogenides in the System Hydrazine Hydrate–KOH

Abstract: The synthesis of unsymmetrical pincer ligands by reactions of diphenyl disulfide and diphenyl diselenide with bis(2-chloroethyl) ether in the system hydrazine hydrate–KOH was accompanied by the formation of 1,2-bis(phenylsulfanyl)ethane, 1,2-bis(phenylselanyl)ethane, and 1-(phenylselanyl)-2-(phenylsulfanyl)ethane as by-products with an overall yield of 23% as a result of nucleophilic cleavage of the C–O–C bond in the initial ether.
