TL;DR: In this paper, a halodemetalation mechanism was proposed, which postulates that donor-acceptor complexes between the reactants, in which the organometallic compound functions as the donor and the halogen function as the acceptor, take part in the reaction, making it possible to interpret the results obtained in the study (generation of radicals), as well as the previously observed generation of carbcations in the given reaction.
Abstract: 1.
The dark bromodemetalation of a number of organotin and organomercury compounds in toluene or p-fluorotoluene initiates the free-radical bromination of the solvents in the methyl group, which testifies to the generation of free radicals during bromodemetalation.

TL;DR: In this article, a method was developed for the reductive dimerization of acrylonitrile to adiponitrile, which does not proceed through the stage of formation of organomercury compounds.

A method was developed for the reductive dimerization of acrylonitrile to adiponitrile.
2.
The reductive dimerization of acrylonitrile occurs at the surface of the amalgam. The intermediately formed radicals are not desorbed into the body of the solution and do not possess the properties characteristic of free radicals in solution.
3.
Reductive dimerization does not proceed through the stage of formation of organomercury compounds.
TL;DR: In this article, a series of fluoro-substituted organomercury compounds, containing phenyl groups, was synthesized, and the chemical shifts of fluorine with respect to fluorobenzene in various solvents were determined.

2.
The electronic effect of mercury-containing substituents is chiefly inductive, while the ability of the mercury-carbon bond for σ-π conjugation is associated with the nature of the substituent at the mercury atom.
3.
The influence of solvents on the electronic effect of mercury-containing groups is due chiefly to specific solvation of the metal atom by the solvent, which depends on the nature of the substituent at the mercury atom.
TL;DR: Piperidine-N-thiohydrazide organomercury (II) complexes were synthesized and the antimicrobial activity of two Gram-negative bacteria, Escherichia coli and Zymomonas mobilis, as well as two infective mycological strains was investigated.
Abstract:
Piperidine-N-thiohydrazide organomercury (II) complexes were synthesized in this study. Spectral (IR, UV, 1HNMR) and TG/DTA analyses were used to characterize the generated complexes. Using thermogravimetric and differential thermal analytical curves, thermodynamic parameters were obtained. For some of the complexes produced, chemical kinetic characteristics such as activation energy, order of reaction, heat of reaction, and apparent activation entropy were determined. The antimicrobial activity of two Gram-negative bacteria, Escherichia coli (E. coli) and Zymomonas mobilis(Z.mobilis), as well as two infective mycological strains, Aspergillus niger (A.niger) and Cerveleria, was investigated.

TL;DR: In this paper, the reaction of Me3SiCCl2Li3 with HgBr2 at −135°C in a solvent mixture containing THF, Et2O, and pentane furnishes the title reagent in 35% yield.
Abstract: [18903-82-7] C8H18Cl4HgSi2 (MW 512.80)
InChI = 1S/2C4H9Cl2Si.Hg/c2*1-7(2,3)4(5)6;/h2*1-3H3;
InChIKey = AWYLSSOYFYYXJM-UHFFFAOYSA-N
(by thermal treatment formally transfers :CClSiMe3 to alkenes, resulting in cyclopropane formation,2 and to silanes, inserting into SiH bond2)
Physical Data: mp 143–146 °C.
Solubility: sol hexane, benzene, chlorobenzene.
Preparative Methods: reaction of Me3SiCCl2Li3 with HgBr2 at −135 °C in a solvent mixture containing THF, Et2O, and pentane furnishes the title reagent in 35% yield.2, 4 For this class of silicon-containing organomercurials, the above approach has proven superior to the more classical t-BuOK procedure1 (see also Phenyl(trichloromethyl)mercury).
Purification: recrystallization from hexane.
Handling, Storage, and Precautions: flame-dried glassware and an atmosphere of dry nitrogen are used for the reactions. Organomercury compounds should be carefully handled, and skin contact and inhalation should be particularly avoided. All reactions must be conducted in a well-ventilated hood.
