Neurotoxicity of organomercurial compounds

Neurotoxicity Research, 2003
Mercury is a ubiquitous contaminant, and a range of chemical species is generated by human activity and natural environmental change. Elemental mercury and its inorganic and organic compounds have different toxic properties, but all them are considered hazardous in human exposure.

The mass spectra of organomercury compounds

Journal of the Chemical Society C: Organic, 1971
The fragmentation of a number of organomercury compounds under electron impact has been examined. In the symmetrical diarylmercury compounds it seems that the first fragmentation is loss of aryl radical to form arylmercury cation which then loses mercury to give aryl cation.

Pentachlorophenyl organomercury compounds

Journal of Organometallic Chemistry, 1965
Abstract The following pentachlorophenyl derivatives of mercury have been prepared; (C6Cl5)2Hg, C6Cl5HgCl, C6Cl5HgCH3 and C8Cl5HgC6H5. Acid attack on the latter two species leads to scission of the C5Cl5Hg and C6H5Hg bonds respectively, in agreement with the C6F5-Hg compounds.

The anodic oxidation of organomercury compounds

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1971
Summary The oxidation of five organomercury compounds at a platinum electrode in acetonitrile has been studied. The products have been isolated from electrolyses carried out in the anhydrous solvent and in solvent to which water had been added. In the latter case, the products are shown to depend on the anion of the inert electrolyte.

Stream pollution by an organomercury compound

Bulletin of Environmental Contamination and Toxicology, 1976
A GC/MS study of residues in general can be very rewarding as shown by some of our unexpected discoveries, but due to the vast ammount of data collected, the best way to effectively use the technique for routine survey work must be with the aid of an interfaced computer complete with library search capabilities.

Exchange reactions of organomercury compounds

Tetrahedron, 1975
Abstract Spectroscopic studies (PMR and UV) have been carried out on mixtures of symmetrical organomercury compounds at room temperature in DMSO, pyridine, and ethanol as solvents. It has been shown that for a range of diarylmercurials, Ar 2 Hg, and di-(acetaldehyde)mercury, Hg(CH 2 CHO) 2 , an exchange reaction occurs with the formation in solution ...

Thimerosal positivities: the role of organomercury alkyl compounds

Contact Dermatitis, 1998
Contact allergy to thimerosal (TH) has not been considered a marker for mercury allergy, since there is a low degree of cross‐sensitivity to inorganic as well as to organic mercury salts. 40 subjects, who previously gave a positive patch test reaction only to thimerosal 0.1% pet.

Interaction of xenon diflouride with organomercury compounds

Journal of Organometallic Chemistry, 1982
Abstract XeF2 is shown to react with organomercury compounds, R2Hg (R = PhCC,p-MeOC6H4, p-Me2NC6H4, p-EtO2CC6H4 and PhCH2), with cleavage of the CHg bond. The products of the reaction are the following: Xe, RHgF (or RHgF/HgF2 mixture; for R = benzyl RHgF undergoes fast demercurization), RF (excluding R = PhCC), R2, and the products of radical, R·,
