TL;DR: In this paper, the mercurial derivatives with a range of ligands having nitrogen, phosphorus, arsenic and oxygen donor atoms could not be prepared by reaction of diphenylmercury and the appropriate ligands in hexane.

TL;DR: In this article, the synthesis and binding properties of squaramide-coated Fe3O4 nanoparticles upon coordination with heavy metals in water are described, which feature selective binding towards Hg2+ and Pb2+ cations in the presence of other interfering heavy metals.
Abstract: The synthesis and binding properties of squaramide-coated Fe3O4 nanoparticles upon coordination with heavy metals in water are described. The nanoparticles feature selective binding towards Hg2+ and Pb2+ cations in the presence of other interfering heavy metals. The binding affinity of the nanoparticles is especially high for mercury and lead cations. The mode of action of the squaramide-coated nanoparticles differs significantly from that of previously reported nanoparticles used as Hg2+ scavengers. The selective Hg2+ sequestering capabilities displayed by the squaramide-coated nanoparticles are related to the formation of organomercury compounds. The solid state structure of the organomercury complex obtained by treatment of a di-squaramide with Hg2+ salts is described, demonstrating the mercuriation of the aryl moiety of dopamine.

TL;DR: By means of a galvanostatic method, it has been shown that diethylmercury reacts with mercury metal to form organomercury radicals as discussed by the authors, a conclusion based on the similarity between the charging curves obtained for solutions of DiethylMERcury and Bromide.

TL;DR: In this paper, the first stage product in the reaction between zerovalent platinum complexes and organomercury compounds was shown to be the first-order product in CF 3 COOH acidolysis with demercuration.

TL;DR: Infrared data suggest that the compounds may contain unidentate pentafluorobenzoate groups, which are monomeric and have low conductances in acetone and benzene.
Abstract: The preparations of some mercury derivatives of pentafluorobenzoic acid and their decarboxylation to give pentafluorophenylmercury compounds are described. Mercuric pentafluorobenzoate and C6F5CO2HgR (R = Ph, p-MeC6H4, or p-MeOC6H4) have been prepared by reaction of pentafluorobenzoic acid with mercuric acetate and RHgOAc, respectively, and methylmercuric pentafluorobenzoate has been made from methylmercuric iodide and silver pentafluorobenzoate. The complexes (C6F5CO2)2HgL (L = 2,2′-bipyridyl, 1,10-phenanthroline, or 1,2-bisdiphenylphosphinoethane) were obtained from reactions of these ligands with mercuric pentafluorobenzoate. The pentafluorobenzoates are monomeric and have low conductances in acetone. Conductances of representative compounds in methanol and pyridine have also been measured. Infrared data suggest that the compounds may contain unidentate pentafluorobenzoate groups.Mercuric pentafluorobenzoate and 2,2′-bipyridylmercuric pentafluorobenzoate decarboxylate at their melting points and the other pentafluorobenzoates decarboxylate on heating in dry pyridine to give the corresponding pentafluorophenylmercury compounds. In acetone and benzene, the complexes (C6F5)2HgL dissociate into L and and bispentafluorophenylmercury.
