TL;DR: In this paper, a solution containing phenyl mercuric acetate was exposed to U.V. radiation, absorbance at 2537 A of the mercury resonance line increased with time, but no increase was observed on the neighbouring line.
Abstract: Vaporization of mercury from organomercury cornpounds has been followed by atomic absorption method by the use of long absorption tube shown in Fig. 1. When the solution containing phenyl mercuric acetate was exposed to U.V. radiation, absorbance at 2537 A of mercury resonance line increased with time, but no increase was observed on the neighbouring line. One of the causes of the loss of organomercury compounds may be explained as the vaporization of mono-atomic mercury produced by U.V. radiationfrom organomercury compounds.

TL;DR: In this article, conditions for the formation of organomercury compounds from other organometallics are outlined, where the phenyl group causes a considerable shift of the redox potential to negative values as compared with the Cr(dipy) 3 3+ system.

02 Dec 1969TL;DR: In this article, a sulfonium salt has been used for methylbenzyl dimers with the formula where N is an integer from 0 to 5 and R is an inert substituent.
Abstract: alpha -Methylbenzyl dimers having the formula WHEREIN N IS AN INTEGER FROM 0 TO 5 AND R is an inert substituent, are prepared by electrochemically reducing a sulfonium salt having the formula WHEREIN R1 and R2 are alkyl or hydroxy-substituted alkyl groups and A is an electrolytically acceptable anion. The reduction and coupling occur at a mercury cathode without the formation of organomercury compounds.

10 Oct 1969TL;DR: In this paper, the authors describe a scenario where a MERCURATING AGENT with an ELECTRONEGATIVELY-SUBSTITUTED AROMATIC ORGANIC COMPOUND in LIQUID HYDROGEN FLUORIDE as the solvent.
Abstract: ORGANOMERCURY COMPOUNDS ARE PREPARED BY CONTACTING A MERCURATING AGENT WITH AN ELECTRONEGATIVELY-SUBSTITUTED AROMATIC ORGANIC COMPOUND IN LIQUID HYDROGEN FLUORIDE AS THE SOLVENT. REPRESENTATIVE OF THE COMPOUNDS WHICH ARE MERCURATED IS NITROBENZENE, WHICH OTHERWISE IS DIFFICULT TO MERCURATE. THE REACTION MAY BE CARRIED OUT AT ROOM TEMPERATURE.
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.
Abstract: 1.
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: In this article, the NQR spectra of halogens in a number of organomercury compounds of the RHgHal and p-ClC6 H4HgX types were investigated.
Abstract: 1.
The NQR spectra of halogens in a number of organomercury compounds of the RHgHal and p-ClC6 H4HgX types were investigated.
2.
In crystals of the compounds studied, coordination interactions arise between the mercury atoms and the halogens. However, when the type of coordination is preserved within a narrow series of compounds, the changes in the NQR frequencies may be determined by the chemical nature of the substituents.
3.
The chemical behavior of the HgHal group depends substantially on the degree of coordination saturation of the mercury atom.
TL;DR: In this paper, the authors synthesized several organomercury compounds of the benzyl series, including 2,6-dimethyl-and 2,4-6-trimethylbenzylmercurichloride, which have a steric hindrance.
Abstract: We have synthesized several organomercury compounds of the benzyl series, including 2,6-dimethyl-and 2,4,6-trimethylbenzylmercurichloride, which have a steric hindrance, as well as of 2-chloromercurimethylnaphthalene.
TL;DR: In the reactions of bis-cis-2-chlorovinylmercury with antimony penta-and trichlorides, dichlorotriscis 2-chloro-and dibromo-triscis -2-clovinylantimonys are formed, respectively as mentioned in this paper.
Abstract: 1.
In the reactions of bis-cis-2-chlorovinylmercury with antimony penta- and trichlorides, dichlorotris-cis-2-chlorovinylantimony and tris-cis-2-chlorovinylstibine are formed, respectively. The substances described earlier as dichlorotris-cis-2-chlorovinylantimony and tris-cis-2-chlorovinylstibine are the cis-trans-trans isomers.
2.
The reactions of tris-cis-2-chlorovinylstibine with chlorine and bromine lead to the formation of dichloro- and dibromo-tris-cis-2-chlorovinylantimonys.
3.
The trans isomers of the 2-chlorovinyl compounds of antimony react with liberation of acetylene at a lower concentration of alkali and at a lower temperature than the cis isomers.
4.
Exchange reactions between antimony pentachloride and R2Hg provide a convenient method for the synthesis of aliphatic and aromatic compounds of formula R3SbCl2.
