TL;DR: In this paper, the oxidation of five organomercury compounds at a platinum electrode in acetonitrile has been studied and the products have been isolated from electrolyses carried out in the anhydrous solvent and in solvent to which water had been added.

TL;DR: In this article, the first molecular hyperpolarizability was obtained for 12 arylmercuric nitrophenylacetylides, and their β was shown to be in the order of 10−29 esu while the λmax in the electronic spectra were around 310nm.

TL;DR: In contrast with many other organometallic compounds, organomercury compounds have been described in which the mercury group is present in the molecule with other reactive functional groups as discussed by the authors.
Abstract: Organomercury chemistry began in 1852 with the synthesis of dimethylmercury by Frankland1. Since that time thousands of organomercurials have been described. One of the most attractive aspects of organomercury chemistry is the wide range of compounds reported in the literature. Organomercury compounds are known in all the major families of organic compounds, and aliphatic, vinylic, aromatic and heterocyclic compounds have been prepared with relative ease. In contrast with many other organometallic compounds, organomercury compounds have been described in which the mercury group is present in the molecule with other reactive functional groups. Mercury substitution is usually compatible with alcohols, ketones, esters, amides, carboxylic acids, aldehydes and most nitrogen containing groups. Since radiopharmaceuticals are usually molecules with complex substitution patterns, it is this special ability of mercury groups to coexist with other functionalities and yet offer enhanced reactivity for halogenation, that makes them so attractive as intermediates in radiopharmaceutical chemistry.

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 paper, a simple, rapid, selective, and sensitive method for the spectrophotometric determination of trace amounts of mercury is developed based on the formation of the orange-red Hg(LAS)2 complex atpH 2.7.
Abstract: The complex equilibria of mercury(II) with Lawsone [2-hydroxy-1,4-naphthoquinone,LAS] were studied spectrophotometrically in 40% (ν/ν) ethanol water at 20°C and an ionic strength of 0.1M (NaClO4). A complete picture of the solution equilibria in thepH range 0.6–4.0 is presented. The complexation reactions were demonstrated and characterized using graphical logarithmic analysis of the absorbance graphs. A simple, rapid, selective, and sensitive method for the spectrophotometric determination of trace amounts of mercury is developed based on the formation of the orange-red Hg(LAS)2 complex atpH 2.7. The effect of interferences was studied. The method has been applied to the determination of traces of mercury in different matrices and some organomercury compounds.
